Ben and Polly
Ben and Polly were rather lucky. Out of all the people who had stumbled into the TARDIS so far, they were the only ones to get back to the right place as well as the right time. Almost to the day! Rather an achievement for him and his TARDIS.
He had been sad to see them go though, as they had been a rather good couple to have around. Polly with her secretarial skill and a light knowledge of technology from her own time period, and Ben his navy skills, they had been quite a duo.
Jamie had been equally sad to see them walk away, stating so out loud after they were out of sight.
He had rather they stayed with him and had tried to urge them to do so, but Ben missed the sea, and Polly wanted to get back to her normal life. So, in the end, he had decided that the best thing to do for all involved was to let them go.
He hoped they stayed together as they made quite the team. But Polly hadn't any navy training, and he doubted Ben would like to stay on land for too long.
Still, he hoped that both of them would go on to lead good lives.
They had led him to a good life after his first regeneration, the only thing he could do in return was to help them start on theirs.
Now, all he had to do to go on living his own good life was to find the TARDIS, which he had somehow lost...
