His first feeling is betrayal. That Raphael would go and tell Don about everything that happened to him - no conference, no organization, no warning.

His second is relief. Aching and livid, the weight of such burdening secrets leaving only scar tissue behind. It burns and is snuffed before Leonardo realizes what a selfish thought it really was.

This is not quite their Donatello (scars are wrong, a little softer a little younger) but they still love him and it will happen, in the end. It can't be helped by anyone except Leatherhead. Leonardo makes a note to thank him again when they get home. For now, he averts his eyes.

"We made a deal with the devil."
