After the smuggler's ship goes thru the anomaly, sensors indicate no power is being generated. Yet the engines are still illuminated, and when they visit the ship, the lights are on.
After the Orville's lower quantum drive is damage, it is still lit up.
When towing the Orville through 2-dimensional space, Ed takes the shuttle to quantum speed. Quantum speed is many times the speed of light. The Orville has a top cruising speed of 10 light years per hour, though the shuttle is presumably somewhat slower. Even if the shuttle were to only travel one light year per hour, it would still clear the distance of the 2-D pocket dimension in a fraction of a second, yet it takes 23 seconds from when Ed engages the quantum drive to when the ship exits the pocket dimension.
The shuttle ECV 197-1 is used to visit the smugglers' ship. It was destroyed when they earlier went to the cannibal planet.
With the destruction of one of its shuttles, the Orville would have been assigned another to keep its complement stable at 2 shuttles. The replacement would have received the same registry number as its predecessor, as shuttles are not unique craft and only bear the registry of the ship to which they are assigned, with a numerical suffix to differentiate them from the rest of the shuttles aboard.

When Isaac and John are installing the device in the shuttle, Mark Jackson's jaw can be seen moving when Isaac is speaking. While Jackson always performs his dialogue as Isaac on-set, the helmet he wears is meant to obscure the movement of his mouth, as Isaac is a robotic life form who does not have a mouth and does not speak the same way a human does.
It has been established that Union vessels and officers use translators when conversing with alien species. When speaking with the Horbalak smuggler Blavaroch, Blavaroch says something in Horbalak that goes untranslated, to which Captain Mercer asks if anyone on the bridge speaks Horbalak. There is no reason that a single line of dialogue should go untranslated if the rest of Blavaroch's speech is translated to English.
The Orville is not able to go to quantum speed to evade the Krill ships because its lower engine is out of alignment. It has previously been established that the ship can go to quantum speed so long as one of its engines is still functional, though its speed and range would be more limited than with all 3 working.
When discussing the idea of an object having more space inside than out, Ed compares the notion to "Doctor Who (1963)'s phone booth." The TARDIS, The Doctors time/space machine, has the outward appearance of a police call box, not a phone booth. Phone booths in Britain were red with large windows on each side. Police boxes were blue with mostly solid exteriors (real police boxes were mostly formed from concrete, however, the Doctor's TARDIS has a wood grain exterior).
The newly-promoted John LaMarr tells his engineering staff that if they get engine efficiency up to 97% by Friday, they call all knock-off (leave work) early and get wasted. It would not be possible for the entire engineering staff to leave early. The engine room would still need to be manned at all times.
