At first, Billy's enjoying the attention, all his worries about Teddy's identity melting away in a river of sensation, and the relief is tangible...he doesn't even mind his costume getting ripped away, he can always fix it with magic later, and there's a certain level of excitement to getting your clothes torn off by a man who wants you this badly...
Not my ideal place for a first time, but it's Teddy...even if it may not be my Teddy...so I really find myself not caring.
He's taking his cape off...it belongs to his mother and he'd really rather not have it ripped up any worse than it already is, magic or not...
Then for some reason, he finds himself face-down in the dirt.
OK, that, I should probably care about. Teddy's never been that rough with me.
Hearing what the other-Hulkling says, Wiccan feels the urge to be sick again. Only now he's not on the verge of vomiting...he's angry.
"Excuse me?! Last I checked, you were the one who went Big Green Rape Machine on me. So yeah, nice try...had me fooled for a second there...but now I know you're not Teddy. No matter what the circumstances, the Teddy Altman I know wouldn't go any farther than I'm comfortable with...and he sure as hell wouldn't shove me around just because he's lost the mood."
Billy gets to his feet, wiping the dirt off his face, and his eyes come alive with lightning.
"Believe it or not, Fakeling, I'm the real Wiccan...and it's time to show you whose kid I really am."
A pillar of blue-white light erupts from Wiccan's hands, thick as his entire torso, with an accompanying roar like a fighter jet shrieking overhead. If Fakeling's armored skin is as thick as the real Teddy's, Billy will have to put all his power behind his attacks to even scratch him.
If he is...but where would the Skrulls get another super-strong shapeshifter? I mean, sure, there's the Super-Skrull, but he's pretending to be Teddy off in space right now.
