I would like to point out that, for the most part, Erich is perfectly amicable; it's only when people try to override him without his input that he gets testy; as for the stitches, well, if the medbay's as top-tier as you've been drooling over, they're likely micromyomer threads; the only thing that'll snap them is a razor-sharp edge.<br/><br/>Edit: See? Bending the rules, by following them. He's not acting as an officer in the medbay, he's the company's 'father figure' where everyone can sit down and have a chat while he's not being busy.
