Watch the last four seasons again, Teyla calls Rodney Rodney all the time. Remember the child-birth scene? I lost count of how many times she called him Rodney. She does it all the time.
She calls him "Doctor McKay" more.
"It's not arrogance if you can back it up"?? What?? Go find a dictionary definition for the word arrogance. It has nothing to do with whether a person can back it up or not, the fact remains, he goes on constantly about how much smarter he is than everybody else. Are you honestly saying that that doesn't deserve just a little bit of piss-taking or goading from the others?
If it's not mean spirited, then fine, but I see no evidence that it isn't.
In fact, McKay sometimes even underestimates his own ability. If he was arrogant, he'd assume he could solve every problem. He doesn't, he often says he can't solve a problem and then solves it anyway.
The fact is that he's irreplaceable, the others are not.
Endlessly bullied?? Can you honestly not see McKay being rude to everyone, shouting at them, telling them how much dumber they are compared to him, acting all superior etc..? Seriously, have you not noticed any of that in the past 4 years?
Waving lemons at him? What, once by Sheppard? Or was it Mitchell?
Both.
If he has to constantly remind people why he is the expedition's chief scientist, a position nobody seems to respect, then that's their fault, not his. They all would have been food for those giant whale-like things at the bottom of the ocean if it wasn't for him. I see no reason why he should treat anyone with respect when he received none from day one.
I'm amazed he even still works for the Air Force considering they packed him off to Russia for hideous crime of being right.
Act like professionals?? This is Stargate ffs, not Law and Order or JAG!
I've never seen JAG, but they don't act like professionals on Law and Order either, but that's a subject for another thread.
