[Oh yeah, Shiro would've died in the first ten minutes of the Battle for Trost. He probably could have survived training intact, with that sympathetic, giving nature--Marco did--but when it came to real battle, it would have killed him. Even now, Jean thinks that's what probably killed Marco.]

[Shiro and Marco would like each other. Jean hopes against hope they get a chance to meet at some point.]

But that's the point, Shiro: you didn't have to. It would have been smarter not to.

[If the monsters in Shiro's dreams had been occupied with Jean, it would have given Shiro time to escape.]

So why are you so convinced that you left your team behind? Everything I've seen of you shows you leave no one behind. Not if there's anything you can do to prevent it.
