Chosen-7

When you exit the wormhole, you break your promise to stay quiet and ask Daughter of Pegasus a question. "Can I name you something that isn't 'Daughter of Pegasus?'"

Daughter of Pegasus looks surprised, but answers, "Well... sure... I'd love for you to give me a name."

You were never very good at picking names (You named your cat Breadstick for crying out loud), so you say the first thing that pops into your head.
