Here's what I think should happen...

Merlin is facing some seriosu evil, ok? then all of the sudden a blue police box materializes in the background. The Doctor walks out: "oops, wrong demention," then he walks back in and the TARDIS disapears.

Merlin and his evil rival look at eachother with confused faces...then they continue fighting.
