I ESL-failed by writing "out of his league" instead of "out of his depth" - and for what it's worth, he would feel that she's out of his league romantically, too! (But then this man even managed to shoot down the normal human girl who confessed to him when they were young, despite the feelings being mutual... let's pour one out for him.)

THAT'S SO MUCH STUFF TO SIDE-STEP... it's not even that he can't handle it, but being unable to do anything about it leaves him hand-wringing! He'll be so damn relieved once she ends up saved from the hibernation. But first he'll try and be there for Rosen like he promised!
