Prometheus EMH: Trapped in the Jefferies tube, alone, nowhere to run. His smug comrade captured by Romulans, EMH mark two had to improvise. Inspiration! He accessed the main computer and simulated a ship-wide bio-hazard, making the computer think there was a microbiotic contamination on all decks.
Prometheus EMH: Presto! He then crawled back out of the tube, accessed the holo-emitters, transferred here, excused the Romulan, saw the dumbfounded look on his comrade's face...
EMH: The end! You know, you really should keep a personal log. Why bore others needlessly? We have o get to the bridge. This ship needs a crew, and we're it.
Prometheus EMH: Oh, trouble. The Prometheus is a prototype. Top secret. Only four people in all of Starfleet trained to operate it. I hope your myriad adventures included piloting lessons... [Prometheus Bridge] ...because there's nothing in my program that will help us fly this thing.
EMH: I've had my share of piloting experience. Actually only two lessons, and they were in a shuttlecraft on the Holodeck, but I showed great intuition. Where's the helm?
Prometheus EMH: You don't know what you're doing, do you? This is not a shuttle and we are not on a holodeck!
