I see "wall-flower" on Crest's shoulder... what about Suspiria?!? SHE's the one who REALLY needs him!
You know, to be honest, I think what Suspiria needs more than anything is to do a little soul-searching on her own. If Crest is keeping his distance a bit, that's probably wise and honorable. Suspiria is not in the right emotional space to start a healthy relationship, and I think it'd be difficult for Crest to be any closer to her and still maintain "just friends" status. A relationship with Suspiria seems WAY dangerous (ridiculously so due to all her power) and also emotionally exhausting right now. Even trying to support her emotionally or protect her could end up being tricky.
But, we'll see, I guess. Anyway, due to recent revelations, Suspiria has become a much more interesting character now, assuming she can escape from being a statue.. I think the Phalanx will want to do something to control her, however, or curb her power somehow. It's interesting that Melter would just hand her over to Crest's keeping, unless he's sure she's really just a statue now.
