I never heard of her but apparently the line and the clip have become an Internet meme.
Since her last name is Röhm and her father is from Munich, maybe it was because she was a Nazi.
Don’t know if her father is a Nazi, but she’s actually from Dusseldorf, not Munich. Plus, it’s unlikely she’s related to Ernst Rohm despite the surname, she certainly can’t be his daughter or granddaughter since... well, let’s just say Ernst Rohm’s personal tastes would never have allowed for it (same tastes Southerlyn supposedly had in fact).
Apparently, she was also in NCIS the past season, either that or the current season (2017).
Well, whatever the case, out of the blue sexuality should not be practiced on TV. Southerlyn’s a good example of why such was a bad practice even back then, not to mention today. If you MUST make a homosexual character, don’t do it out of the blue, make it very clear they are that.
