Sure.
From time to time I think all of us see something in a fic that even the author did not intend. This may be one of those cases here.
To me, this fic had that beautiful circular symmetry that I have noticed before, like one of yours (at the moment, the name escapes me) where Mick and Beth, and Josef and Simone, had to be separated (or they would be killed by the Legion). Simone accepted it, moved on and Josef worked to negotiate a deal for Mick and Beth--that ultimately cost him his life, but secured the safety of the L.A. Tribe from the Legion en perpetuity. It began with Mick and Beth in a relaxed, romantic moment and ended the same way.
In this story, while Mick was asleep in his freezer and dreaming, there was this lovely paragraph that (I thought, foreshadowed that Mick was in the process of working out the logical answer to their separate togetherness.
Quote:
He didn't need to hear the chambers of her heart contract; he knew it quickened for him.
He didn't need to see the tiny muscles in her eyes tighten as her pupils dilated; he knew her desire flared for him.
He didn't need to gauge the changes in her body temperature; he knew she burned for him.
As much as he longs for humanity, does he not long for love at least that much? And has he not found it here, in his Beth?
Also, although it is not alluded to in this story, it remains the one of the huge unspoken truths of Moonlight, that when a linespan extends for centuries, if one is careful, technology will perhaps unlock the secrets of what they are, as well. Since a Cure was devised centuries before by combining botanicals, and this is the root of most of the drugs currently in use, could not a Cure be in their future, as well. I'm really astounded that this aspect has not been explored more in fanfic. I think it would be fascinating.
So, to answer your question more directly, although Mick has this fantasy of walking hand in hand with Beth into the sunset, he has already been thinking of their love not depending on the responses based in her humanity. Because of the time involved, the chances of Mick seeing a Cure, or at least some form of treatment to mitigate the troublesome 'symptoms' are much greater for him. He can think in terms of the possibility much more easily than Josef (perhaps). Would Beth be willing to take the chance? I think she would.
To me, Mick's mind was moving toward turning her in the future.
Or that is what I saw.
