Reaction
Some fans speculated that Penny wasn't straight when she was first introduced, given her butch appearance and relationship with Della. After her in canon lack of attraction to earth males, the fandom was split between headcanoning her as a lesbian, and headcanoning her as aroace.

When the director revealed her orientation, many were happy but disappointed being forewarned it would not be an ongoing plot. There was also understanding as they were under specific strict guidelines by Disney: "I had certain constraints I had to work in to get this across"
