It is baffling to me. There have been many ships that I have not liked. There have been ships that I feel make the source silly and less interesting than it could be. But if it's canon, wishing doesn't make it any less canon.

Was this person a hardcore 9/Rose shipper? I can see someone saying that to make their prefence more important. Personally, I'd like to think the Doctor would love Rose no matter what regeneration he was in.

I pretty sure that they liked Nine/Rose, but I'm not sure whether or not they're a hard-core shipper. I'm always a bit baffled by people who only like either Nine/Rose or Ten/Rose, really. Because it's a continuation of the same relationship, just with some new quirks.

P.S. I love that Doctor/Rose being in love is now canon.

I know! I love them so much.
