Setting dangerous Wonderland precedents, for one. Logistics, for another. He wouldn't go easily, and when he comes back to himself, he'll remember...

[ ray trails off, trying to find words that aren't "remember murdering their interim captain and his own friend in cold blood just to prove that he doesn't care." what else could he get up to in wonderland with his new best friend, psycho speedster? ]

I think the less he feels he needs to prove that he's serious, the less damage he'll cause.

[ man it'll suck if/when he's proved wrong huh ]
