OK, so this one is a bit of a leap, but just imagine how awesome it would be if it actually happened! Torchwood is being developed by Big Finish now which means that it's being produced by the same team behind the ongoing Classic Series adventures. Is it really that outlandish, then, to theorise that there might be a crossover on the cards...? Obviously it won't happen straightaway, since they'll no doubt be focusing all their efforts on establishing Torchwood in its new found audio universe before playing with the strings, but there's no reason why it can't happen at some point in the foreseeable future. Suffice to say, the word "fangasm" wouldn't even come close to describing the unequivocal joy that would behold the respective Doctor Who/Torchwood fandoms if Jack & Co teamed up with the Fourth Doctor on an Earth shattering escapade that defied the realms of time and space itself. It's the stuff that Whovian dreams are made of.
