Don't think that Laura is overly paranoid... but she just wants to be very sure that neither of these machines are capable of further combat. Snikt! Laura is just going to remove their arms and head to be very sure that they are not still dangerous.

She glares death at Kanji for his little outburst, then turns to the new door. Given how their last time through a door went, and this room was (relatively) safe. "You and Takane's body remain here, I will clear the room before Takane and I attempt to gather information."

With that she heads to the new chamber, hoping that Takane's mind can follow. On the plus side she isn't bleeding anymore.
