Series 9 will end with Jeremy accidentally killing Mark.To cope with this, he changes his name, goes on the run and takes up a new profession, lecturing about geology at Manchester University. This explains the reason behind all of Dan's gibbering insecurities - he's a murderer.
Nancy will return in Series 9It's the way Mark mentions her near the end of Series 8 completely out of the blue. She hasn't been mentioned at all in any capacity since she last appeared in Series 4 and Jeremy has so many other exes he could have mentioned instead. It seems so random the only explanation I can think of is that it's a bit of foreshadowing.
Gerard isn't deadHe said he was playing 'the long game' but he can't have seriously thought he still had a chance of stealing Dobby from Mark...unless he had something insane up his sleeve! Gerard doesn't have much going for him besides his intelligence, and with his nerdy interests it's very plausible he'd be inspired by his comic books and video games to pull of a magnificent cunning plot like faking his own death to destroy Mark & Dobby's relationship (which seems to be working) and then when Dobby's all sad and alone, she's so happy to be with him again that she won't even question how he came back from the dead. Oh, and his sister is obviously in on it too.
Mark and Jez are demons from hellSeriously, watch the series from the begining but with this in mind and it's so obvious. They are demons from Hell just trying to fit in here on Earth. Other such demons are Don Danbury, and The Gang.
Something horrible is going to happen to Mark and Sophie's babyJust going on the nature of the series.
Sophie's baby is Jeff'sShe just said it was Mark's because he is easier to manipulate and take advantage of.
The entire show is an extended flashback by MarkHe's explaining to his psychiatrist/prison guard/executioner why he murdered fifteen close associates in cold blood.
Mark and Jeremy are secretly Reality Warpers, but they don't know it.The trouble is, they always expect, secretly, to fail in their endevours, and thus reality warps to meet their expectations.
Jeremy will end up rich and famous, Mark will end up poor and dependent on himIt's been played with in the series and seems to be one of Marks many many neuroses
When the series finally ends, both Mark and Jeremy will be happy.Fairly obvious; considering the series is their perpetual unhappiness, when it eventually ends the writers will Pet the Dog and give both of them a happy ending.
Either Mark, Jeremy or both will die in the series finale.Peep Show has enough of a dark streak about it to make a Blackadder ending possible. Possibilities include some sort of murder-suicide pact, hostage situation, or disaster like drowning. That or one of the duo pushes the wrong rival too far one day.
Jeremy secretly does have a job. He's a lecturer at Manchester University.Mark just works such long hours, he's never noticed. Jeremy doesn't want anyone knowing he's a geology geek, so pretends to live off his mum and Mark.
