….I actually watch those two the most the more and more I watch that movie. I honestly don’t know if they wanted romance or not, but they most certainly wanted to make it clear that Erik was determined to have Raven with him, whatever was going on. If you watch his facial expressions a certain points, he definitely has his eye on her, and wants Hank out of the picture, because Hank has the power to mess it up. I don’t think in the romance capacity, but moreso with his “cure” and his lack of appreciation for Raven’s blue appearance.
Honestly, that scene where she’s in his bed, all I can think of when I look at his face is “ha ha, gotcha!” Because that’s the point where he pretty much gets her on his side entirely as an ally.
(Not to say he didn’t want Charles with him as well. He most certainly did. Whenever Charles is in he room he barely even acknowledges Raven. But Raven was always going to end up an ally to Erik and I think Erik knew that….Charles there was always doubt…and I rambled.)
