Despite all of our differences, though, we have one very important thing in common.  

We were all trained by the best.  

So I originally tracked down Batman Annual #13 for a short Alfred-centric tale at the end of the issue, and I only recently went back to read the main story and was surprised to realize the Robin depicted in the prologue was actually Jason, and not Dick like I'd assumed.  Not only is it a Jason appearance (sporting yellow long johns at that), but there's also a Two-Face meeting, and a team-up with Barbara as Batgirl, though we sadly don't see them really interact.

Moreover, although Bruce initially chides Jason about the snowballs, he ends up "borrowing a page from Jason's book" and uses one (admittedly laced with mace) to defeat Two-Face, which is kind of cute.

"He replaced me?"

He's so delightfully bitter.

"...I know he's not you."

"No he's not.  Maybe he'll be better than me."

"The dynamic duo.  You guys were the real thing.  You love it."
