I think Simmons is "the one," at least right now. Skye was only in the picture because he didn't really know Simmons yet. I don't think Triplett is a threat, nor do I think he'll bend for an "easy" woman if she happened to come by.I feel like Fits just wants SOMEBODY. I mean, he was making the eyes at Sky before it became clear that Alpha Agent wanted her. May's outta question so there's the one female I as a viewer thought was his sister for most of the season... and now he's getting out Alphaed again.
What I will say about Triplett is that he still brings a very ominous feel to every scene, his allegiance still feels ambiguous. I'm not entirely convinced, even if he says all the right things.
