"Then lets follow through with it. What's the worse that can happen, more people don't like me?"
She isn't quite as concerned about Avalon not knowing what she's talking about, and it's clear enough that Avalon's the one that doesn't like her, but for whatever reason, she doesn't elaborate. She can take the hint from what Pepper had started when the tobacco perfumed lady of 'mystique' enters the room for the second time.
"I would be open to meeting your sister. Oracles help us all if she's the same as you."
She makes it abundantly clear that she's joking, and adds a good natured laugh and smile to hammer it home.
"I haven't found anyone with a similar enough purpose to mine yet where I'd want to call them family anyway. What better foundation than an actual family. I can think of one other person that might be out in the cold that we could invite along too. You remember the guy that was talking to me at the club. You two seemed to get along, so why not invite him along too. Could use a little variation in the origin stories."
If that's a comic book reference, she doesn't know it. It's just a great way to subtly refer to path awakenings. Origin stories. Right?
