Why did Malcolm think he could defuse an alien bomb?
When that Romulan mine attached itself to Enterprise Malcolm said he was the only one with the training to defuse it but it wasn't any weapon humans had seen before so why did he think it would be something he had experience with?
They'd never heard of the Romulans before that point.
Also, when that limb attached itself the hull and it shot thru his leg wouldn't that have compromised his suit and all his oxygen would have leaked out and he'd have suffocated or the pressure of being out in space would have crushed him? Or does Enterprise work under completely different laws of physics than we do in the 21st century?
