'A Slight change' How certain episodes would be different, sorta, if other things happened early, or late, or ... well you'll get the picture. Seperate from the previous chapter.

Episode Tag: 4x? "Message in a bottle" - Prometheus, Hirogen Relay network, and a little EMH modification added on...

Astrometrix, USS Voyager.

"Doctor, I've managed to make it so that you can keep all your additional... ah, modes..." Harry spoke.

"ECH?" He asked.

Harry nodded, "Yes." The Doctor nodded back, and Harry continued. "Your command codes should work on the starfleet vessel, since I've also added special circumstance ones."

"Huh?"

Seven spoke up, "Essentially, codes that will alert the vessel you are transferred to that you are from a stranded ship."

"There are codes for that?"

Amused, Captain Janeway nodded, "We're not the first to be stranded far from home, and not the first to attempt something like this. If you need to, you should be able to take command, if such a situation crops up."

"Of course. Well... I feel the urge to say something profound, however I thankfully do not have Mr Paris' eloqy-" The Doctor disappeared.

"Seven." Kathryn chided.

Seven merely raised her right eyebrow, and continued to work on sending the doctor across the galaxy.

USS Prometheus

The Doctor glared at the EMH Mk 2. "I must take control of this ship before we get ourselves killed."

On the screen, a battle raged between 3 starfleet ships and 2 romulan warbirds.

"How?"

the Doctor shook his head, and spoke up, hoping it would work. "Computer, engage Program Voyager-Emergency Command Hologram."

The blue of his uniform fizzled in that holographic way to red, and he moved to the captains chair. "Computer, engage evasive maneouvres, Pattern Delta-3. Armed phasers, lock targets on the romulan warbirds. Return fire only."

The ship shook, and immediately the EMH Mk2 was shocked to see their own ship fire back, shot for shot but no more.

'Course, then both surrounded them and the larger warbids still outgunned them, well, sort of.

"Computer, what is Multi-vector assault mode? It sounds as though this ship should seperate to, attack from multiple vectors..." The ECH spoke.

"Affirmative. This ship is designed to seperate into 3 distinct independant vessels, while also capable of being remotely controlled from the main bridge of the upper saucer module."

"Open a channel to the Romulan ships." He spoke, and waited for the tell-tale sound of a channel open. "This is the USS Prometheus to Romulan warbirds, you have 10 seconds to cease your attack and retreat, or we will fire with impunity. End transmission."

the EMH Mk2 of the ship was aghast. "Doctor?"

The sound of a channel opening was heard, and the ECH merely said, "5 Seconds." the channel closed... and the other federation ships moved into formation, not firing whilt eh romulans too had ceased firing to contemplate their actions...

Only to fire a full barage of torpedoes at them.

"Shields at 74 Percent." the computer announced.

"Initiate Multi-vector assault mode. Target the romulan ships, Disable one, destroy the other, and co-ordinate with the other vessel's tactical officers..."

After a minute, the battle was over, and the Doctor called, "Computer, reintegrate the ship, and set course for the nearest Starbase. relay intended course and request escort from the others."

"Incoming hail."

"Onscreen."

Q pondered that change. Wondered what the long term effects was, and looking ahead, saw it wasn't as big as he'd thought, although Dr Zimmerman did look to creating an 'ECH mk 2', although that failed.

Seems Voyagers' ECH was a one off, for the time being...
