Here we have Girf's sister in Halo Reach.
Lopez thinks he killed her, but Grif won't believe it unless you produce a corpse.
"Once when we were kids we were ice skating and she fell through the ice. She was under there for three hours, and when they pulled her out, not only was she still alive, she was pregnant."
"You know how circuses have a bearded lady, and a fat lady? Well, my Mom plays both, 'cause she's like, super-talented."
"Which one is the hippie drive? Is that the one with all the knobs or is it the other one with all the knobs?"
Sister: Is this the kind of thing you guys do all day?
Grif: Pretty much. Just run with it. It's the only thing that keeps you from going insane from boredom.
Sister: Yeah... or we could raid the medical supplies for morphine.
"When you're old and gross, you're probably going to die, and that's kind of sad. But when you think about it, all your friends are probably dead too. And if they're not then they're definitely old, and knowing old people is even sadder than being dead. So, anyway, whatever. Peace out."
Doc: You speak Spanish?
Sister: Uh, of course I do, it's the year twenty-five hundred and I'm from America.
