There might not be as much of an argument as anticipated, because as aggravating as it is, he also knows it's true. There is a higher standard he's expected to meet, not just from his instructors and the Professor, but his own. "... I know." He does, which is why he exercised what he felt was almost saintly patience! "But there is also something to be said for teaching someone the value of respecting another's personal space and possessions in a situation that doesn't leave them maimed or dead."

Like biting, a helpful whisper in the back of his thoughts suggests. One good bite and he'll never get in biting range again.

The thought made his teeth itch and that chemical bitterness return across his tongue, but as soon as it's suggested the interest in doing so is replaced by disgust. He wasn't interested in touching anyone more than necessary, never mind biting. He's not as strong as he was, and Avan simply not being part of a military Sephiroth knows doesn't mean he's not part of some other one. Or skilled in some other fashion that would be suddenly and unexpectedly trouble in a murder attempt. "..Coming here was a bad idea."
