The Avengers finally have a chance to make thing right after 5 years after the Snap. During the Time Heist, you and Steve were assigned to heading to Vormir for the Soul stone. Steve wasn't too thrilled to see the Red Skull again, especially how he ended up here, nor was the Skull thrilled at all to announce Steve's name, but there were more pressing matters other than old enemies seeing each other again. Skull explained about there needing for a sacrifice; a soul for a soul, go figure.
You and Steve briefly look at each other. His expression stern and determined. "I'm sure we both know what's going to happen here." He says, his steps already directing towards the edge of the cliff. "I've had my run anyway." You would be shocked, but knowing how much of a true hero he is, you're not exactly all that surprised.
