Series 5 ended with Amy getting married to Rory. Series 6 ended with the Doctor getting married to River. Presumably, Series 7 will conclude with the TARDIS tying the knot with Captain Jack’s Time Vortex Manipulator.
I just hope that, in each case, this was the wedding ring:
According to the ring’s designer, it’s a “Police Box ring with a tension set 1CT Princess Cut center stone. The three round stones is the Police Box sign, the two sets of four baguettes symbolize the windows, and a small princess cut below that to symbolize the instructions found on the front of the Police Box.”
It’s also completely nonexistent, a digital mock-up by Tumblr Pathetic Parapatetic.
All I’ve got to say is that if somebody were to make this thing, then I’d say “I do!”
…and then would have an awkward conversation with the Queen B afterwards.
