This might be fun.
It’s real simple just name a companion that the person above you remind you of.
It doesn’t have to be a regular companion; anyone that has ever traveled or been close with the Doctor can be used. Example Donna’s Father Wilfred Mott.
Here’s a good list if it helps.

I guess since I started this I’ll just have to wait to name someone.
