Delenda Est - S3-E11
Revealing mistake: When Dylan and Tyr head to a bridge where supposedly the power source is located as well as Rommie, they start to cross the bridge. As the camera is facing Dylan and Tyr, the next scene two aliens teleport in. Rewind the video to facing Dylan and Tyr and play in slow motion. Watch the bottom portion of the screen and notice the top portion of one of the alien's head go into the camera as if the aliens walked into position for the teleportation.
The Prince - S2-E10
Revealing mistake: As Eric is rushing on his ambitious start while talking to Dylan and Tyr, the hologram of Andromeda appears to talk about a ship approaching from Slipstream. Eric tries to continue, but Dylan asks him to wait. Eric turns around and you can see his reflection mirrored onto the hologram.
