C does sound like a good way to raise the pressure of the Jill plotline without immediately detonating it in the middle of the Yuri plotline. She'd have to be pretty good to beat Aria's senses though.
And 3 makes the most sense for the meeting. It'd be a bit dull to mindwipe everyone who learns the truth and as long as Yuri has no proof there's not much she could do even if she weren't willing to keep it secret. And since she likely will keep the secret, I'm sure Aria would agree it'd be a waste to erase that connection.
