<Lt. Cmdr Mortimer, Main Bridge>

"Going to yellow alert"

"Captain, security teams are in place"

"Captain, transporter room 2 is not responding. I'm detecting unauthorised use of the transporter."

We thought to monitor the Klingon vessel, but it seems that somebody is using ours! Do we have a spy aboard working for the Klingons?

"Security to transporter room 2. I'll meet you there."

"Mr. Macdougall, you have Ops"

Mortimer enters the turbolift, holding the doors for four seconds in case anybody else is going to join him. 

(To turbolift, once anybody else is inside) "Transporter Room"
