I know this is a silly thing, but it really irked me, and I wanted to vent a bit before I actually messaged the person for being so rude towards others.

If you weren't being so damn childish about it, no one would care. But, since you're publicly harassing artists because "that wouldn't happen because of my head canon" then you need to back off. That's YOUR head-canon, not theirs. They don't know your OC, nor do they care. If they want to ship those two characters, let them. You are not the "original" and only role play account of that character; get over yourself.
Also, her dad's name is Alejandro NOT whatever the hell you came up with. He's the Adventurer, in the multiplayer - they have the exact same last name, and he even mentions her in his audio log after playing him 3 times. It's pretty easy to put two-and-two together if you read character bios. Lore people, it's there for a reason. (When anyone tries to explain that to you, you get overly defensive. I get it, it's your head canon, but stop trying to pass it around as fact.)
(Also, leave that Felicia RPer alone - from what I can tell it was a random attack for no reason. Why are you randomly cussing her out? She is a real person behind that character, you know.)
