During Game Time with Meg she stated that Monty was the reason why they are together, as he introduced them to each other during PAX Prime.
One of her cosplays was as Gavin's character from X-Ray and Vav, though with the outfit altered for a female. She did this cosplay alongside Ashley, who was cosplaying as the other main titular character with a similar outfit alteration.
She is openly bisexual and has talked about her bisexuality in her YouTube videos.
Her and Ryan seem to have a very strong friendship; Meg was the only person Ryan follows on Twitter, and their relationship is apparently so close (likely due to them working together on both The Know and Free Play) that some people in the office (mainly Geoff) joke about it at Gavin's expense.
Meg is one of eleven siblings (some are adopted).
Meg's first attempt at cosplaying was at the age of 14, her design wasn't based off a character - but was an original idea created with what she had available.
According to Free Play: The Newlywed Game - #30, Meg('s):
Favorite color is pink.
Majored in History in Mass Communications in college.
Wants to travel to Japan.
Favorite videogame of all time is The Legend of Zelda: A Link to the Past.
Biggest pet peeve is people who chew with their mouth open.
Biggest fear is the dark.
Childhood nickname was Meggy Moo Moo.
Meg once accidentally flashed her private parts in a Free Play episode. The exposure is covered up in the video.
Meg is known to have her hair in multiple different colors, likely related to her cosplay work. She is one of two people from Rooster Teeth to do so, Achievement Hunter's Jeremy Dooley (since shaved bald likely due to a dye job gone awry) the other.
During RTX 2016, Meg dressed up as her RWBY character, Neon Katt.
