Recall and Recoil (джен)

Just when Steve and Sam are ready to give up the hunt, they find a Winter Soldier waiting on their doormat.
He's fine. Steve's fine. They're both just fine. (By now Sam's more than a little familiar with the stubbornness of self-deluded super soldiers and super assassins, so he lets it slide. Mostly.)
OR
Bucky is not a feral cat (except he is), Steve would never (consciously) try to to pay penance for letting Bucky fall, and Tony Stark has totally not been sitting by his phone waiting to get an SOS signal from Steve.
