It doesn't make him happy, because in the state Chara's in, he'll probably be pulling double duty. Of course, that is what he'd offered. Blood on his hands already, he oughtn't stop now. Why, he'll just wait for an enemy to pose a threat and dispose of them.

That is NOT his function.

Quietly, he moves in front of them. Towards the actual entrance of the reclamation depot. Due to his...aggressive negotiations with the outer Savrii guard, they don't find much resistance while they're outside. Still, once they're in...all hell is likely to break loose. So he tells himself that whether they wish to be touched or not, if they pose a threat, he will have to do what must be done, and hope they don't compromise this entire mission.

You set boundaries, but you don't follow them. How good of you, Mettaton.

No, this was different though. He was saving them if he picked them up and took them away from harm.

Whatever he has to tell himself, right?
