When he had first heard Minervamon had shown up, Shark wanted to go and give her a piece of his mind, but he refrained after hearing the pleas of his partners. It has him caught in a moral dilemma. He's angry for everything she's done, but at the same time, he knows that she didn't do it out of wickedness and out of good intentions.

He doesn't like that.

More accurately, it pisses him off. He hates it. He hates her presence. Most of all, however, he hates the fact that he can't bring himself to hate her and be done with it.

So there's nothing more he wants with Minervamon then for her to go away.

"You're better. Now get out."
