After looking through, and watching, all the episodes up to the end of season 3, these are the episodes I think I'll be able to use in this series, the one's with the (M) next to it means I want to use the episode and I might be able to use it. So it's a Maybe.
If you think I can use other episodes please say so and pitch to me why, and possibly how. If you want to know the reason why I'm not using a certain episode please ask and I'll explain why.
