Carson? I don't think his marrying chances are that high, right now. But I think it's mostly because he's currently a runaway more than anything, so I wouldn't bet on it.
I don't know about Talmid, but I am always excited to see romance, whomever it is about... well not everyone. It has to be interesting in some way (and the characters likeable). I mean for instance Captain America's romance in Civil War no one really ever cared about! :P
