This is part “spelling out everything to make Leif comfortable” and part “Thorn practicing his around-the-house vocabulary.”
…yeah, that last strip was the April Fool’s Day post, we’re actually starting the party now!

Anybody want to guess which characters are going to show up with a plus-one?
Quick, someone find the earlier strip that this is a callback to!
