I imagine the Master must be rather bored at this point. He's is stuck on Earth, but he can't taunt the Doctor as he needs to get his plans further on the way first. So he amuses himself with poor Alison and Peter. You are right he has toys rather than companions.

As always, thanks for reading and for spotting typos. I would write this story even if no one cared about it, but it means much to me that you do! <3
