Keep whichever ones ya like!  I've got a ton more where they came from.<br/><br/>Presumably the rebels, even once they get into Lab #144, wouldn't even necessarily know that Steinman is there, let alone what floor he's on.  The others would be more focused on finding the source of the Call and getting the hell out of Dodge before GenCorps forces arrive, so Tam could focus on finding Steinman and doing whatever it is she's thinking of doing!
