Yeah, there've been couples out at Finches on fairly regular occasions, with no issues.
It doesn't matter if someone is part of a couple or single... unstable is unstable, and they'll find something to lose their shit over. Whether it's some other dude checking out his girlfriends ass, or a full auto burst, or a twig fell in front of him.
"War must be, while we defend our lives against a destroyer who would devour all; but I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend: the city of the Men of Numenor, and I would have her loved for her memory, her ancientry, her beauty, and her present wisdom. Not feared, save as men may fear the dignity of a man, old and wise." - J.R.R. Tolkien
