I really really hope so..at least for ade& navid and liam and naomi. i don't care much for silver and dixon,because i don't like dixon. but there is-at least in my opinion-evidence that those prior mentioned couples will get back together eventually.

1) writers love to screw up endgame couples. they build up this whole epic story for them but obviously can't keep them together through out the whole running of the show because that would make them boring and is just working if you are nathan and haley;)so instead they torture us.

2) Navid& Ade: they can't let everyone fall in love with this couple in season 1 just to mess around with them and breaking them up in season 2 for good. they know it wouldn't do any good to the ratings since those two are obviously meant to be together because without navid ade is just acting crazy.plus the writers know how much people love them. with keeping them apart for a couple of episodes we can fall in love with them again;)

Naomi and Liam: pretty much the same. they torture the audience by always keeping them apart but i'm totally sure that after building up that much tension the two will end up sooner or later
