1) I have cosplayed a lot! I've done Spider-Man (Far From Home black and red suit) Ruby Rose from RWBY, Billy Loomis/Ghostface from Scream just to name a few! I wanna get a lot more and try doing more cons!
2) Funnily enough, Miguel recruiting her to the Spider Society wasn't her first rodeo with the multiverse! An ex professor at MIT was making a portal to try and find his lost students, but was doing it illegally (obviously). Aubrey fought this guy and he pushed her inside, and she found herself in a universe where there was an older her and Boston was the big city! So When Miguel recruited her, she sort of already knew what she was getting into with other variants of herself, but she was still pretty excited about learning more about the Spiderverse specifically!

Thank you for your question!!!
