I have this weird headcanon that Garrus' father is an excellent cop, but a terrible father. Not in the physical or mental abuse sort of way, but in that he totally does not get his children. He tries his best but he ends up being "one of those" weird fathers that embarrass their children by trying to be cool.
It makes me lol.
So here is Vakarian Sr. trying to warn his estranged son of the dangers of cross-species intercourse. With old C-Sec case files. YARR.
Good to see embarrassing parents translate across species. I'm not sure why but I have a feeling Garrus got his romantic "skills" from his dad. All professional C-sec cop but when he first starts trying to court the future Mrs. Vakarian he starts stumbling all over himself.
I bet poppa Vakarian is doing it on purpose. Why? For the lulz, of course.
