he tells him he's missed him, even though that makes no sense at all. a smile lights up his features as he looks upon him, hands gripping in just the right places, firm squeezes that say: i've missed this, touching you
it only reaches his eyes because he's such a good liar (but he does miss touching him, all the time. loves him even when he hates him. loves him even though he never misses him. loves him even though he could replace him without a second thought.)
honest where it matters, of course, enough to convince them all he's the epitome of truth then later, lying through his back teeth, easily, like chewing his favourite sweets, no difference in expression: insincerity masked by a perfect illusion of sincerity
"what reason would i have to lie to you?" he asks "i don't need to lie to you; i don't care about you" because everyone knows the best lies are saved for loved ones as we manipulate ourselves into believing "this is for the best"
he tells him he's missed him, even though that makes no sense at all. clothes shed, a trail to the bedroom, a private place where both can be themselves: here, he's genuinely honest stripped bare in more ways than one.
he tells him he loves him, and it makes perfect sense even though his love is tainted, empty; better to say he cares, but that's love for him― as close as he'll ever be.
he smiles when he hears it, "i love you too", and this time it reaches his eyes, even though his heart doesn't race like a lover's would.
