"Alicia took care of it. I'll be fine." That's not strictly speaking true - she might have patched the wound, but there's still the bodily need for recuperation and the blood loss factor, however minimal he was able to keep the latter - but Seth looks about ready to collapse on his feet.

He continues, just as calmly, while offering his good hand for support: "And I'm not the one who can't stop shivering."

True, Daniel's not feeling great. But Seth's definitely been pushed to his limit. More accurately, he was pushed to his limit months ago and then kept at his limit for an unhealthily extended period of time, and he's long overdue for a crash.
