Your renegade video was awesome.

RE: The "I thought you were dead" and nicknames questions.
Jane: She shrugs and try not to think about it. Mostly. Sometimes when she's not so good mood she goes on with the undead thing. "Brains!" and stuff. Only person she ever talk about it seriously is Liara.
"Brainsssssss!!!"
Jane calls Liara to her blue goddess sometimes, but other than that she doesn't have any nicknames for her.
Jennifer: She's pissed. Mostly she goes with the "I got better!" or "I was. I feel better now." And want to beat the living daylight out of the person who asks the questions. Sometimes she first beat them and then answers. She has some issues of her being brought back and all that.
Jennifer calls Liara "love" or "My love" , but she doesn't have any real nicknames for her.
Amy: She's oddly enough ok with the whole thing. She's not religious person and just believes that everything happen for a reason. What she believes is quite close to what Shiala says to her before she gives the cipher. She's also my most paragon Shepard and always polite to ppl. Sometimes I think she does that to infuriate me.
Amy calls Liara "Li." or when she wants to be playful. "Doctor T'Soni."

Lise: She hates it when ppl ask her that. Since it's obvious she's not dead. Lucky ones get glare and maybe some sort reply that could be count as growling.

Not so lucky ones get punched or shot. Whatever the case one thing is similar. Her biotics flare to life when she's asked about it.
Lise doesn't have any nicknames for Liara. She just uses her name.
