"When did I stop?" slips in Tidus's unasked for reply to that: You really are playing my knight again now. Just because he can say it, even more convincingly* with a puff up chest and confidence to match it.

(*no, he still sounds like a joking dork as always.)

But that next part does sound like a challenge--a challenge that has him looking back the way they were leaving from, the opposite direction from the real exit.

"Why? You saying now you wanna keep going?" Tidus brings his face in close to Inigo's, without shoving it in there or giving him no room to move. Just so they're face to face! "I'm game if you are."
