Yeah, that is definitely who he thought it was. This is just wonderful. Dirk is never going to flashstep without being 100% certain of what the people around him are doing ever again. Just as soon as he's not being crushed under the alternate universe version of his bro.

When it feels like he can breathe again, Dirk tries to shift back, or at least get his face away from Dave's... but apparently that isn't going to happen.
