I thought as well that Tully was like Angie, both are needy but Tully is more extreme perhaps. Both are pretty good TV.
Jade is actually more like Layla, empty character dependent on showmances for her story. No doubt the same girly teens were/are behind both.
Drew's support will be from a similar group and will be shallow just like Josh's was last year.
There is no true Estelle this year, though the producers are trying to push Mikkayla as being the underdog character. She isn't actually as big an underdog at all. She's also involved in plenty of gossip and isn't as quirky.
Ben is a geek like Bradley but without the funny brat-like character he had.
Tim is as contrived as Michael in playing the fool.
Heidi is cliquey like Stacey was.
