but they are completely unrelated lol
i dont suck the richard of career heros as you seem to. a title is no reason to be proud.
Depends.
An odd comparison would be like a cookie-cutter's shape.
They let us know (or at least think we know) what shape the dough will be when we cut it.
In a sad roundabout way, this ties in to the career that Dallas has. It's sort of like positive stereotyping (if that's even a thing.) where we know since he's a Fire-Fighter, we assume the things he does, like the one in the OP, are just natural to him.
tl;dr: Since we know he's a Fire-Fighter (and know how they usually act/are portrayed) this information isn't utterly useless because it ties in with the event that happened.
