1. It was kind of a chain reaction of things. The pair supposedly had a history (not known how deep, but anyway...) on the outside and not necessarily a pretty one. So they had a mutual disliking because of that. Also there was little snide comments and ridiculing from the housemates about her appearance time to time (she had big breasts) and her personality (she was a loudmouth and sweared quite a bit)
Earlier in the day they had a water melon explosion task, where you use rubber straps to explode a water melon. After the task had finished, they had a playful rubber band war. After the rubber band thing was already over, an older male housemate (not the one she slapped) shot a few rubber bands towards her. The second one hit her in the eye and she began to hold her head and said "i´m hurt". She went to the diary room about 20 minutes later and said "it hurts". Later when she returned, she said that a doctor (in the diary room) had examined her eye and it was damaged quite a bit. More so that she had to wear an eye patch for the next three days and take pills fir it. Because of the medicine she was given, she was forbidden to drink alcohol for that time period. So that made her upset.
The male housemate (the one who she had the history with, not the one one who shoot her in the eye) said something like "you started the thing, so if you can´t take the joke, boo hoo for you". She got more upset from that after being upset already and went to the diary room again.
Later in the evening there was a war of words fight about 50 or so minutes before the incident between them (the girl and the boy with a history), where they both changed insults to each other. She got upset when he talked to other female house (which was her friend) in a drunken slurry way wanting to know something and not making sense and she thought that he was making her friend feel uncomfortable. After that it was peaceful for a while.
Later she wanted to go sleep, but someone was in her bed already. She said/asked many times for a housemate to get up and go to the his/hers own bed, but nothing was happening and the woman kind of slurred something and maybe ridiculed her a little bit with an older woman HM. She got very angry/upset of that. The one was on the bed, had a kind of a little spat with her earlier, so she was already upset at that.
So then when he was in the kitchen airing her thoughts and feelings (she was threatening to hit the woman who was in her bed), a very drunk male housemate (the one she had the history with) began to provoke her. She got more angry, but the man provoked her still trying to grab her and saying "you should go to the diary room and calm down, thinking she was being overly ridiculous. The female housemate said "don´t touch me" repeatedly, but the male housemate didn´t listen. Finally after a few insults and words, she slapped him and was called to the diary room. He pushed her towards the diary room door and then after regaining she slapped her again despite a female housemate that tried to separate them all the way through.
They both exchanged insults when she was going to the diary room and he said also a few times that: "If i really wanted, you/she would be on the ground", despite being told not to by the other housemates. After a few moments, she was gone and the situation was done. The male housemate continued to insult the female housemate, when he and the other housemates were talking about the situation about 2 hours or so. Later the man who was slapped went to the diary room and delivered a message that she (the slapper) was removed for violence towards a fellow housemate.
2. He told all of the housemates that he was going on the day his day was held.
One thing you need to know, it was his day that day (On this season, we have had housemates day´s, where a selected housemate would have a day of their own with all of their wishes granted. What kind of food to eat, what kind of activities to do, what kind of music to listen, what kind of party to be held etc...)
So the painting was one of the things he got to do on his day. He spend many hours doing it and he also asked all the housemates to put
one fingerprint to the painting (since his painting represented BB house, his experiences in it and it´s people in someway) so that they all were a part of his work.
Later in the evening there was a party, with his choice of drinks and food and music to listen. Later when the party was on it´s way to end, a housemate decided that Andy´s painting lacked something. She then decided to "improve it", (One other housemate also did an extra fingerprint on the painting, without asking.) and decided to do do several (at least ten) fingerprints to the painting without any permission from the painter himself. So then a female housemate (incidentally the the slapper in the first question) ratted her out, because she was his friend. The painter was furious, insulted the one who did it, pushed her in a moderate way and kicked a bedroom door very hard. (It left a visible mark). He was called to the diary room, where he was quite some time. During his time there, an altercation between the culprit and the teller of the incident. The culprit asked quite a few times: "Why did you tell him what i did". The rat was defending herself, but the culprit wasn´t having any of it and called the rat a little devil. They had words and some of the other had words with her too, but she defended herself. The situation continued a while, before she went to the bathroom.
Then he (the painter/musician) came back from the diaryroom. Then the altercation continued. She was trying to say sorry (kind of dumb way), but he wasn´t going to have any of that. He insulted her and she provoked to hit her. He went for her, but wasn´t going to hit her. He has said (i´m not sure if he said then), that he would never hit a woman.
Someone broke the situation up and then the culprit went to the bedroom and the painter went to smoke. A while later the painter came from the smoke and he and some other housemates inspected the painting and thought if it was possible to fix it. The painter said: "No, fuck it. It´s ruined" and dropped the painting from the pedestal to the ground. After a little while he was called to the diary room, and thus removed from the house. The culprit and the other one had went to the diary room and refused to return to thehouse until Andy was removed.
3. The dog was probably a condition of participating from the housemate that had it, meaning that without it she wouldn´t have came to the house. So the producers gave in. Not sure what the owner thought, probably nothing.
The dog was a Jack russell´s terrier six years of age.
Before the fireworks, the dog was just in playful, perky and fun loving mood. When it happened, he got starlet and ran to the bedroom and went under the bed, staying there. After the incident, he was seemly very stressed, agitated (he was shivering and his eyes were wide open) and breathed quite heavily. In a scared mood, so to say. The party kind of died down after that.
They walked the next morning. I´m not sure, because after the incident she was in the diary room quite a long time, before coming out, so it might have been then. In the early morning (about 8-9 AM) she had backed her things and the dogs and had outdoor clothing on her. She waited and waited holding the dog on her lap and then finally left through the diary room and never came back. So it might have been then also.
The producers admitted that it was an information cut on their part and that they were supposed to inform the housemate that possessed the dog about the fireworks, but the information never reached the right people. They apologised, but the damage had already been done.
4. On season 1 we had 1 walker (She felt trapped inside the house). On season 3 we had a housemate walk, because she found out in the house that she was pregnant and wanted to leave because of the child. Also a female housemate walked was allowed to leave, when she heard that her grandfather had died. On season 4, a housemate just was removed or walked and the reason are still unclear why she left. On season 6, one housemate just left because of personal reasons. On season 7, a female housemate, escaped through a nest rooms emergency exit on day 3. I´m quoting World of BB:
"he left because she felt like she didn't fit in with the rest of the Housemates." Adding to that, she felt trapped and just didn´t like it in there. She also didn´t like the electric suite task that was on the day before. On season 8, a female housemate disliked the house atmosphere so much that she wanted to leave. 54 says later a male housemate left because he felt tired of the house and missed his child.
We have plenty of ejecteés too, which is not a good thing. Almost every season we have at least one ejected housemate. Season 1 is the exception.
