In "Dear Dave", Lister gets a letter from a previously unknown ex-girlfriend called Hayley Summers. He says he was with Hayley "when he was trying to be a rock god", which presumably means when he was in Smeg & the Heads. She worked in a bank, they spent Saturdays watching Zero-G football . . . this relationship is presumably taking place on Earth before Lister has joined Red Dwarf. 3000000+ years later, a mail-pod arrives containing a letter from Hayley Summers, addressed to Lister onboard Red Dwarf. In the letter, she tells Lister she is seven weeks pregnant and he might be the father. Lister doesn't immediately discount it as impossible, so that means there is a maxiumum of seven weeks between the last time he slept with Hayley, and him joining Red Dwarf. And he obviously never got this letter the whole time he was aboard Red Dwarf pre-stasis, so mail-pods must have been dysfunctionally slow even then. And all the letters Lister has got before now must have been sent even earlier than Hayley's letter. In Waiting For Godot, Lister says he's been "with the company" for eight months. I suppose "with the [JMC]" doesn't necessarily mean "aboard Red Dwarf". So Lister must have been with the JMC on Earth while he was with Hayley Summers, then joined Red Dwarf within weeks of Hayley Summers dumping him. Unless Lister meant he was onboard Red Dwarf for eight months, in which case he musn't have got any mail. Correct me if I'm wrong, but does this mean Lister was only onboard Red Dwarf for seven weeks at most before going into stasis? The mail-pod also contains another letter where she has gotten a paternity test and Roy is the father. So that mail-pod must have been sent very soon after Lister joined. Well, at least the letters within were written very soon after he joined. But I'm pretty sure we've had previous mail-pods contain letters for Lister. Mail-pods sent earlier would arrive earlier. So what's going on with the mail-pods, why are mail-pods with earlier letters arriving later. At what point will the mail pods run out because presumably news of the radiation leak got back at some point, meaning people stopped writing letters and the space-post stopped sending the pods. So the mail-pods must all be from before or just after the radiation leak when family hadn't heard. We know that the rest of society heard about the radiation leak because Howard Rimmer says "We heard you went down with that rust-bucket Red Dwarf" or whatever.
