There have never been many occasions in his life Sarge felt warranted a smile, and this is most definitely not one of them.

But as things are now he isn't, and all he could do is tell them that they are probably killing him with this and maybe threaten to lock them up in a room somewhere until they get along.

It's his own way of telling her 'you're welcome, but it's nothing'.
