Remember when that Skrull-As-Reed in SKRULL KILL KREW became a big tube and swallowed one of them?
Well, Reed can do the same to Norman. Unlike the Skrull, though, he'd know to spit out the gun.
Yo be perfectly honest, if Norman's gotten unstable enough to miscalculate this much, if he's gotten this far gone, it means his Goblin side has come to the fore and he's starting to get addicted to the risk, which also means he hasn't long before his fall.
