There's also some clumsiness around the idea that failing at a hetero relationship is a sign one is gay, which isn't necessarily the case from any direction you'd care to take that on. This is a time-traveled version of the character, which might put the idea more in the realm of commentary on the fluidity of sexual attraction.
