Time Trick (comic story)

 was a Doctor Who Adventures comic strip published in 2013.

Summary
A psychic invite to a Time Conference is mistakenly received by both the First and Eleventh Doctor with explosive results if the two should actually meet and cross their own timeline.

Plot
A serious, but little bit grumpy Eleventh Doctor, arrives with Clara Oswald having accepted a psychic invitation to be a guest speaker at a Time Conference on Refkeet Nine. But it appears the invitation was also received by the First Doctor who has arrived with his granddaughter Susan Foreman. Clara recognises the First Doctor from the Doctor's own time-stream but is warned by the Doctor that they must not meet up or risk crossing his own timeline for fear of things get a bit ... "explody!" While the First Doctor is led away by the conference hosts the Doctor and Clara discover that the conference is a trap and, in a caged area, a Nuppino horse is being abused and being 'trained' to teach the Doctor a lesson for his meddling in time.

The Eleventh Doctor isn't recognised and with Clara's help set about freeing the beautiful, bright and kind Nuppino Horse from its captivity. As the First Doctor is led towards the main hall, to "be treated as he deserves" the Nuppino Horse — now released from his chains, runs amok chasing the hosts around just to give them a little scare! In the background the Eleventh Doctor and Clara watch as with their plans now in tatters the First Doctor turns on the hosts and gives them a proper dressing down for their senseless and shameful treatment of such a gentle creature. The Doctor makes the final point to Clara that he's not as grumpy as he used to be!
