I love the implications that Poppy's favourite Brozone member (after Branch, ofc) is Clay.
If you think about it, she doesn't act nearly as fangirly or awkward around John Dory or Bruce, and the latter was the Heartthrob and is still quite attractive!!
I don't know enough about Boy Band culture to be sure, but you'd expect most fans' favourite to be the hottest member, not the Funny One. I think it that says a lot about Poppy's character and why we love her :)
