Am I imagining that she is sharp and he isn't in all of these?  There is no way he moved in every pic.  I tried focus and recompose though and am wondering if somehow that contributed.  I just don't know why one would be sharp and one not.

This one definitely is a DOF issue.  The boy's right (our left) shoulder is in good focus, and it's on about the same plane as the girl's face.  The boy's face, however, being a bit further forward, has missed out.

Focus and recomposing is tricky. You can't move that much, as we are only talking a few inches of you moving. If you really wanted them both sharp, I would have been around f/5.6. Maybe even as far as  f/8...but I'm more at f/5.6 for these shots. You could have tried f/6.3 or f/7.1 too. Don't worry about the background being blurry and wanting to use f/4 or f/3.5. The reason is, and it looks like you used your 70-200, is to use compression to your advantage, meaning you want to take a few steps back and zoom in to suck in the background, which will help blur things and maintain enough DoF to get both relatively sharp.

Also, what Shutter Speed were you at? What focus mode?
