Bro-code is being broken - War of the Roses
Avery thinks Lucas is cheating on her so she wants to do War of the Roses. Avery thinks this because one of Lucas' friends told her so. When we do War of the Roses, we typically get our answer by who they send the flowers to. Well, in this case, Lucas ends up sending the flowers to Avery...which is what he is supposed to do. Usually, that would be a case-closed happy ending but Avery isn't taking that for an answer. Turns out, Dave could be the bad guy.
