Jim (to Blair): We just took a brief detour to the Sandburg zone.
Simon: Allright, look, Sandburg, this is a crime scene. I don't want you touching anything.
Blair: I know! I'm an anthropologist, I've been to excavations before!
Simon: You know what? On second thought, stay out here!
Beverly Sanchez: Spent the last couple of days thinking about you and me.
Ellison (nodding): And?
Beverly: Well, maybe we should just try being friends.
Beverly: Yeah. What do you think?
Beverly (shaking hands, smiling): Friends.
Ellison (smiling): With potential.
