So, I just beat Arrival with Titra. That was fun, I got alot of headshots when she cloaked and used her widow. Lia kept wipping singularity and reave on their asses (changed from barrier, since I knew reave would come in handy)
Some Lia:

"Such a badass power! Biotics and blood, mwahahaha!"

"Kenson, get the bloody camera out of my fac1 I'm here to rescue you, damn it."

Lia: I don't trust you, Kenson. No offence, but working around Reaper tech and not getting indoctrinated. I don't buy it.
Kenson: No worries, commander, your right. I'm indoctrinated, want the Reapers to come, and will blow myself up. Just be ready to shoot.
Lia: Just once, can't I get away from crazy people?

Lia: *under her breath* Goddamn it, so much for blowing up stuff with Jack and Grunt.
Hackett: What was that?
Lia: *louder* Nothing...Sir.
Here's a few of Titra:

Titra: I can do that. But, what if I took a thief and an assassin with me. Nobody would know we were there. Trust me, they're good.
Hackett: No, commander, alone.

Titra: Sir, I don't think I have my dress blues anymore. Last time I saw them they were on the SR-1.
Hackett: Shepard, I'll send you a new set then, just...be ready.
Titra: Yes sir.
