If we don't see Martha again I'm okay because her story is resolved, though I do love the idea of Ten not being retarded and actually managing to maintain a friendship with someone -- seriously he could just pop over for tea! She would accept this! -- but clearly that won't happen because it interferes with his important schedule of watching Lifetime.

Rose's story is over, too. She doesn't need to come back.

That said, Donna's storyline needs to be resolved in a nicer way before Moffat takes over and we never hear of Martha/Donna/Rose ever again ever. SO, DONNNAAA.
