2x04 Pants on Fire

I could kinda sense this in the previous episode too, and I'm really hoping I'm wrong, but it seems that maybe there will be more between Casey and Izzie? It's just suspicious that Casey and Evan's relationship is going way too good, like even if there are some bumps here and there, they are able to talk it out and resolve it relatively quickly, within 1-2 episodes max. So I'm thinking (or _over_thinking lol) that maybe Casey will want something more exciting like her daytime drinking with Izzie, who, btw, totally gets her situation (basically having to be a mom for her siblings).
Like I said, I'm really hoping I'm wrong but something does feel fishy about this situation for me. Evan is the sweetest guy I've seen in a TV show since many-many years (or ever), and not in the I'll-do-anything-for-you-my-queen way but in an actually believable, real-life scenario way. He's funny, loving, caring and patient. He wants to solve their occasional problems with Casey, but he's not being pushy or a dick about anything. He knows boundaries - and that's probably the best way to describe him. Their chemistry with Casey is super good. So if they end up breaking up, I'll seriously debate to continue with this show because that would be the dumbest decision ever to separate them.
