Tsubasa Tiger, Part 4

Tsubasa awakens in the next day at the Araragi house and finds out that she was possessed again. As she leaves the house, she is stopped by Koyomi's mother, Mrs. Araragi. The mother explains that while having Tsubasa as a guest is no burden to them, she should not consider the Araragi family as her own. Mrs. Araragi also explains that adverting ones eyes from the truth isn't running away from the problem, mentioning Tsubasa's strained relationship with her own parents. Later, while walking through a park, Tsubasa encounters a man named 'Mr. Episode', who is a half-vampire and once almost killed her.
