I hate love triangles with a passion. Like you said, they're adults not kids. Let them act like it.
Let Ric get back with Ava and give them an honest change. The show can't waste a goddess like Ava on a drip like Sidwell.
I really hope Jason doesn't "die" again. Unless his death is faked so he can dig up dirt without Sidwell/Cullum knowing it. But also only if he tells those closest to him what he's doing. First on that list should be Danny and Jake but, ya know, I'm sure he'll tell Sonny first, then Carly, then Britt, then he might get around to mentioning it to Danny.
