In X-MEN UNLIMITED v2 #4, a reference is made to Juggernaut's "bust-up with Spider-Man" "last year." I don't believe that this fight scene was ever published...until the past week.

In a flashback in this week's AMAZING SPIDER-MAN #629, Spidey fights the Juggernaut, and the fight leads to William Nguyen's series of misfortunes. I believe that scene -- ASM 629 (5:1-5:5)-FB -- is the "bust-up" noted in XU2 4.
I have the bust-up scene on the calendar as a BTS scene, but I will change that to ASM 629 (5:1-5:5)-FB.

There's another flashback to Spidey's and Juggy's first battle in ASM 230. The flashback contains new material showing Juggernaut's month-long effort at digging himself out from his concrete prison -- ASM 629 (8:1-8:5)-FB.

Here's the impact on chronologies:

More flashback material in ASM 629 involves William Nguyen and Juggernaut and precedes their appearances in ASM 627-629.

Oh, and that COH 3 reference above? The MCP's listing for that issue includes only heroes, not the many villains who appear there. I'll try to get to addressing that soon.

I thought Willian Nguyen getting fired was supposed to coincide with the original fight between Spider-Man and the Juggernaut, in ASM 230?

The references are to two different battles, the first one way back in ASM 230 and a subsequent one involving Nguyen only "last year."
