It appears that when choosing a destination to travel to next, the Master hadn’t taken into account the fact that you two may run into a past version of himself, what with the whole time travel thing. Fortunately or unfortunately, that’s what happened. While on a planet together, you and the Master come across a younger version of himself. Not younger by much, only two regenerations ago. You recognized this regeneration, you remember liking his messy blonde hair.

What you didn’t expect was for the two versions of your alien companion to start fighting over who gets to take you home with them.

“I haven’t gotten my turn with them yet, I think I should have them!”

“Be patient, you idiot! You’ll have your chance!”

You sigh i’m distress, not sure what to do to de-escalate the situation.
