Jack was seriously considering heading back to the SGC in order to find out who had approved sending this McKay guy on a mission and then killing him or her, regardless of the consequences.
Daniel was absorbed in trying to translate the symbols on the keyboard of the strange device. Teal'c was patrolling the various exits. McKay and Carter were heatedly arguing about whether something she had suggested would work.

"What she's suggesting is never going work. It is impossible to connect-" Rodney stopped talking as Jack pulled out his sidearm and aimed it casually at Rodney's head. "What was I thinking? Of course Major Carter's idea is going to work."
Jack nodded, satisfied, and lowered his gun.
