"Hey," he says mildly, worried at his failed attempt to lighten the mood, and now it's his turn to put a comforting hand on Daniel's shoulder. He's not generally that quick to resort to physical comfort, but when Daniel looks like this it happens almost instinctually. Daniel comes across as so much more put-together than Seth, so when he's not, it's just really jarring and Seth gets the intense urge to fix it.

"I was only offering. You don't have to explain anything," he continues gently, watching Daniel carefully. "But, uh.. You offered to be there for me, you know? Just saying, if you wanna talk, or anything, not now but at some point, I.. You know, I'd like to return the favour."

He's not doing a good job at comforting, it sounds terribly awkward and overly sentimental, but he hopes the meaning behind it carries.
