She did say there could be goblins.
I've addressed Tedd's pronoun preferences in a few places, but it's a frequently asked question, and I wanted to get it into an actual comic (not everyone reads this fancy text down here, or my various declarations elsewhere, of course).
I also felt like it would a jerk move to just describe Tedd's preferences and leave it at that, because what is desired by Tedd is not typical. The assumption that Tedd's circumstances would be typical might be a bit much, but as Amanda points out, plenty of people aren't used to they / them, and I didn't want to muddy the waters further.
That said, it all felt a little "the more you know", so background goblin fight nonsense.
