You’re welcome to send in some companion love of your own. Just remember that whatever you send in must:
a) focus on one or more companions (or the actor/actress), not the Doctor
b) must be positive towards the companions discussed and not derogatory towards any other companion; tell me why you love Martha Jones, not why you hate Rose Tyler.
c) As great as Doctor/companion ships can be — trust me, I have my favourites — this isn’t really the place for them, so something that focuses more on, say, Eleven/River as a ship than on River herself doesn’t really belong on this blog. On the other hand, companion/companion ships of any and all kinds are welcome, so send me your Ponds, your Mickey/Martha, your Jack/River, et cetera. This one is going to be a bit more discretionary, since if you want to talk about why you love a companion, his/her relationship with the Doctor might be part of it, and that’s fine. So I dunno, just use your best judgment.
Pretty simple! Enjoy.
