Charne - Will be brought up in discussions about first evictees, how female housemates who stand out always go first, how producers shouldn't make the mistake of hiring a character rather than the person underneath etc.
Ryan - Won't be talked about much outside of references to his relationship with Estelle. He may come up in general conversations about showmances and he may come up in conversations about people having multiple in-house partners (eg compared to Mirabai with Damian and Brodie; Glenn with Michelle and Geneva; Layla with George and Sam).
Sarah - Could be talked about in a similar way to how Rita is talked about.
Ray - Forgettable aside from the effect he had on forum members. Not quite boring enough that he would be put in the same category as Gaelan though.
George - Could be talked about in the boring housemate category with Gaelan, or could be remembered for his showmance with Layla and especially her multiple pairing with both George and Sam. Will also be brought up in the "vote to save" vs "vote to evict" argument.
Ava - I had to check Wikipedia to see who was evicted after George, I knew Bradley didn't go that early. She could be remembered as an example of a boring intruder chosen for looks and to pair up with one of the guys, rather than for personality. And she could be remembered for how much the audience didn't like the full-on nature of her relationship with Josh. Or she might simply be forgotten.
Bradley - I think he'll be remembered fondly, as the awkward, geeky kid with a good heart, or he could also be remembered for how the producers tried to rig it for him.
Angie - She might get remembered for her outbursts and for the fight with Layla.
Stacey - She'll be remembered for how the most entertaining housemate doesn't always win.
For those left:
Ben - Will be remembered as an entertaining housemate and will also be brought up in conversations about gay housemates.
Estelle - She'll be remembered in the same category as Camilla, Farmer Dave and Zach, as nice enough people, but really nothing special as far as BB housemates go and not worthy of the pedestal their fans put them on. She'll be remembered mostly for how carried away her fans got.
Layla - For being British, playing the ditzy card and playing the game the way British BB is played. She'll also be mentioned in conversations about housemates having multiple in-house partners.
Michael - Will be remembered for his Machiavellian scheming, for his hook-up with Estelle and for the producers' bias.
Sam - Could possibly get a mention with Gaelan, otherwise only as Layla's second pairing.
Zoe - If she had left a couple of weeks ago, she would have been remembered as a fun-loving, but slightly boring country girl. Now she'll be remembered for her obsession with Michael and unfortunately she'll probably be remembered for giving Estelle a final push across the line.
Edit: I forgot Josh. He'll be remembered for his how he left obviously and will come up in conversations about Emma and her father.
