Spoilers for the ending of Lost in Space season 1 (2018):
In the season finale, we see the land rover park in the spaceship and the camera reveals some sort of glowing object attached to the bottom.
I kind of felt like this came out of nowhere but, according to Wikipedia
the robot had hid the alien ship's engine under the land rover.
Do we see this happen? Have we ever even seen this engine before it shows up beneath the land rover?
