"Hey, don't underestimate the good use of a doorstop. You may get to make that happen sometime anyway," Majima said. And if it wasn't entirely clear he was making the play on words of stopping up a door instead of holding one open, which might be more clear with his next words. "We might need one if'n we ever have to break out of here the hard way. But don't go thinkin' about makin' that kinda sacrifice without other attempts first. Can't have you hoggin' all that glory either."

Or, what he may have actually been thinking, don't go making sacrifices where I won't get to see you again. Majima was selfish enough to admit to himself, at least, that he didn't want to be alone in this world. He didn't know if Kiryu would read into that, kinda hoped the guy wouldn't, but that's what he probably meant. He was just a coward deep down after all.
