Well back when Rosa was alive it happened often, greatly because Noah had a thing for Rosa more than Isobel...
Thankfully the show has been renewed, wouldn't mind Kyle leaving and staying gone, hoping that Max comes back soon or isn't really dead after all he's supposed to be the savior in Noah's words...then again Isobel lied to Noah in that mind world where nobody is supposed to be able to lie...but Noah wasn't in that world if memory serves when he said that about Max, who could call down lightning to the palm of his hands that didn't kill him, maybe it helps bring him back, wonder how they'll work Rosa back into a world that has changed so much since she died and all...
And Isobel had fallen for Rosa before the latter died, and Rosa knew about it and that she was an alien...
