"Of course you were!" you reply at once. "I saw how hard you were working. You did all that research just because you wanted to. That's pretty amazing."
Robin doesn't quite manage to meet your eye, but you can't miss the smile on his face. He sniffs and wipes something off his cheek.
"Thanks," he says softly.
