Midsleep he wakes races to the bathroom startles Loki who worried hasted after. It'd happened that morning too in the car with Steve he'd demanded they stop climbed out throwing up intensely.
Loki hurried to his study devised an elixir bid him drink it to counter the relic's effects, said it'd wear him for an hour or so pulled him back to bed refrained from chiding him but was angry. However unconcerning or mild the symptoms it's not okay, he…He understands why, but…But he worries, too much it dawns on him that morning after breakfast when Steve calls Tony tells him, Howard's looking wants him for an op and this time won't take no for an answer, as all week Tony'd faked being sick and Bruce backed him up whilst they worked on those gadgets. He was fine with it for a long time to a certain point, contented being able to watch him, hear him, help him when needed – but no. No and he's being rash he knows, selfish even – he doesn't care. No, enough, yes he wants him to stop wants him to walk away, wants him here, with him, all the time and away from a constant, imminent danger, enough – He keeps a placid face as Tony hangs up, locks onto his gaze an anticipate look in browns as then he tells him:
"…When I come back I wanna talk…You asked me what I wanted," closer he came cupped Loki's face, an answer – the answer he needs from browns speaking: "…I want you, Loki."
Such relief in his chest it instantly in his eyes reflects a smile retorted and his lips Tony took in a kiss reciprocated strongly, deeply Loki pulls him close, and even with what he'd said so inexplicably difficult it was that day to let him walk away even supposing it'd be the last time, still.
But that it'd be the last time reassures him.
