Tikka To Ride - S7-E1

Corrected entry: Lister says that killing your past self will cause you to die, thus making it impossible to go back in time to kill your past self in the first place. So how was JFK able to kill himself at the end of the episode? If he killed himself, he would have still survived as he wouldn't have been unable to go back in time and kill himself in the first place, the same was as the crew survived their attack.

Correction: It's a temporal paradox - a mainstay of time-travel stories. As time travel doesn't exist, writers are allowed to handle these things in their own way. In this case, the Kennedy from a timeline where he survives is brought back to shoot his prior self. The moment that the bullet hits, reality shifts onto a new timeline, parallel to the other one. The living Kennedy's timeline no longer exists, but it doesn't erase the fact that it did exist - the crew don't lose their memories of the events that took place there and so forth - and so there was a Kennedy who survived Dallas who came back to alter the timeline.

Tikka To Ride - S7-E1

Corrected entry: At the beginning, Lister is giving the ship's log speech. When a light shines on his head you can see the shadow of a microphone on his forehead.

Correction: Maybe it's the microphone of the camera he's holding? It'd be a bit pointless to talk to a camera to make a ship log if there weren't some recording device attached to it.

Tikka To Ride - S7-E1

Corrected entry: In the episode 'Tikka to Ride', Lister tells us he has recently passed his 28th birthday. He was 25 in 'Future Echoes', meaning that all the episodes up to this point have taken place in around 3 years. However, dialogue in 'Back to Reality' and 'Holoship' (which took place before 'Tikka to Ride') says that the crew have been travelling for around 4 years.

Correction: They have been travelling at very rapid speed, and relativity is starting to show its effects. They may think they've been in space for four years, but they have only aged three.

Tikka To Ride - S7-E1

Corrected entry: In 'Tikka to Ride,' Lister explains why people can't kill their past-selves. Near the end of the episode, we see JFK killing his past-self with no after effects.

Correction: There ARE after effects: JFK disappears.
