I don't take credit for the following, but it gave me a good chuckle. For the record, I like Kaidan, but fun can be made at his expense
Imagine Kaidan being in a public place, possibly in a bar surrounded by his army buddies, when a news report about Shepard comes on.
He proudly states how he has a thing with her, and that they're gonna be together soon some day.
"Shepard, hero of the citadel, has become the centre of another controversy..."
Kaidan will laugh and say about how she's always getting in to trouble.
"...After it was discovered that she has been having relations with a Turian outlaw."
Everyone laughs at Kaidan and rubs it in. The Turians laughing about how how they have stolen Shepard from him.
Kaidan leaves without even finishing his drink, and he can still hear the laughter after the door has shut and he's walking down the street.
But even this exit brings no respite.
For several turians have followed him out of the bar, and continue to point and laugh at him, all the while pelting him with dextro-amino bar nuts.
They follow him down half the length of the Ward, picking up other bystanders along the way. The crowd starts to get bigger and bigger, and the harsh, flanging laughter of the turians is soon joined by the melodic giggling of asari, the snorting and wheezing of volus, and deadpan statements of derision and merriment from elcor.
"Ha ha ha, now we know why you humans almost lost your 'First Contact War' to us, after 'First Contact' with a turian your women couldn't wait to jump ship!"
"She left him for a turian! Goddess, a turian! How pathetic, I'd rather mind-meld with a hanar!"
"What a loser!"
"Earth-clan, I wonder how this was even possible." Wheeze. "Your mate thought her chances of reproduction better with a turian than with one such as yourself." Deep breath. "I suppose that means even *I* could try my luck, given the competition. Heh heh."
"Mocking rebuke: Your mate has likely deserted you due to your inability to satisfactorily pleasure her in the manner expected of a male of your species."
"Sarcastic offer: May I interest you in this genital enlargement program?"
They hound him mercilessly all the way to the elevator. He collapses inside as the doors close on their mockery, finally alone in his misery.
"This is Kalisah bint Sinan Al-Jalani reporting for Westerlund News. Tonight we'll be bringing you an exclusive interview with Commander Shepard and Garrus Vakarian, the turian with whom she is reportedly..."
Or not.
