But, this isn't my ship or anything." A tiny smile, because he has no idea that she already knows it isn't his ship.

Jack steps a little out of the door, gestures towards the front of the ship. "I can probably explain a little better if we step outside." The engine is still and silent, the normal subtle vibrations of the ship in motion aren't present, so they have to be landed or docked somewhere.
