Loki almost looks shocked for a moment, but quickly hides the expression behind a mask. He attempts another step towards Heimdall but stumbles, falling on one knee. His hand is clamped over the massive wound in his chest. Blood drips onto the ashen sand.

Odin banishes Heimdall from Asgard for committing treason against the throne one too many times, and the Watcher is left bereft of purpose. He thinks to follow Thor into battle against Malekith - but then his eyes catch on an odd sight on the ruined world of Svartalfheim. Loki, alive but gravely wounded and alone.
Heimdall saves Loki's life after he's stabbed by the Kursed and they have a talk about life, death, and forgiveness.
