final warning

Iron Man stands in a dimly lit, industrial chamber, extending his right hand forward as a bright energy blast emanates from his palm, then retracts. Captain America appears in a separate shot, standing in a snowy, outdoor environment with a determined expression, fists clenched. Iron Man is then seen from behind, standing in a large, dark chamber with smoke and light flares, his arms outstretched as he stands over a fallen shield. The scene concludes with two tombstones in a grassy field, one for Captain America and one for Bucky, with their names, lifespans, and humorous epitaphs.
