Ajax's Helmet? (spoilers, maybe)
That'd be my guess. The jig is up, after all.

Q: How do you wreck an Abrams?
A: You crash into another one.
Ajax heard from Serge that helmets are SO last season.
It may mean that the old Ajax wore the helmet, so he could get away with not wearing one. No one knew who he was, so the new helmetless Ajax could have been the old one.
I'm really awful at explaining things.

He couldn't breathe in that thing!
I got what you're saying. The letter mentions the helmet, and says that they both have a "similar look" in the outfit... doesn't say he actually put the helmet on, so you may be right.
It's probably just more likely that he took it off once he outed himself.

In his letter, Ralph Valetti says that he was able to assume Ajax's identity because he always wore a helmet. However, in game, he is NOT wearing a helmet. Are we assuming he just ditched it when the truth came out, or what?
