It's a horrendous watch and he wears it all the way through - it must have been tan lines (have been looking through PoF pics for iconing and am amused by the fact that a surprising number of the Master and Timanov ones are oddly slashy (as Timanov belives the Master is the chosen one and is gazing at him in wonder) - would have been a perfect pairing for FUF those two). And I definitely agree that Fivey's uniform fetish would certainly not stretch that far.

If they can fire weapons in the TARDIS in Earthshock than the TARDIS's circuits must be faulty hence both violence and sex must be allowed in the TARDIS. That's my excuse and I'm sticking to it!
