That's the impression I've gotten, kinda; just hoping that overrides their anger at John (presumably) marrying a woman on the show. I actually kinda don't want him to be married when Sherlock returns, just because...like, it's awkward if he finally moves past his grief and gets married and is happy again, and then Sherlock comes back and throws everything off. I'm afraid it'll give the reunion, like, the wrong feel. Or the implication will be that John's really not over it and he's just using Mary to distract him from his grief, and then she'll get tossed aside when Sherlock comes back. Neither one is awesome to me. But I'd like to think the show can do it right...maybe.
