I may have mentioned this before, but sometimes I imagine 2 characters played by the same person are actually the same character, and I imagine there is a story that links them. For example:
Angel to Booth (Angel becomes mortal, loses his memory and becomes a sniper, and then FBI agent)
Jonas Blaine to President David Palmer (Blaine eventually retires from the Unit, and changes his name for Security Reasons, he assumes the identity of a Decorated Colonel, and uses his war hero status to successfully run as a US Senator
Rose Tyler to Belle de Jour (Rose gets so frustrated at not travelling around in time and space with the Doctor, that she decides to find her adventures between the sheets, and becomes a high class call girl)
If I am feeling realy adventurous I might link 3 characters together in a single arc...
DI Jack Regan to Inspector Morse to James Kavanagh QC (After years as a hard arse Detective in the capital, and giving evidence in a case where he is forced into a new identity Regan decides to move to the more idylic surround of Oxford, he is now jaded, and resents his new life taking it out on his new partner Lewis, eventually his past catches up with him and he has to fake his death again, this time he's out of law enforcement for good, but he can still play a part in the justice system defending the innocent, and occasionally prosecuting the guilty.
These are just some I've come up with, and are only outlines, it's something I normally do when struggling with insomnia, or on the bus, or whatever. Anyone else do this? And no, I don't have any with starlings or snails in them...
