Disrupting Friendsgiving

Petra Stark is familiar with cross-dimensional travel. Six months ago (well six-ish, time is tricky) she returned a Robin who had accidentally fallen through his dimension and into her's back where he belonged. So when she is facing a dangerous man with a poorly made inter-universal ray gun in a warehouse rigged to explode, she does the only reasonable thing and reprograms the machine to transport her to a safe dimension. Naturally, she chooses Robin's, but she doesn't quite end up where she thought she would. Or when she thought she would. Instead, Petra finds herself transported into a strange cave with seven teenagers eating turkey and potatoes at a dining room table. Or: Petra Stark transports herself into the Team's Friendsgiving meal.
