You were holding him tightly.
Morpheus had been talking about how it might be best for everyone to leave, as he couldn't guarantee their safety now that the Benevolents were after him. — “ Hide in other kingdoms until it's safe to return... after my death. ”
You refused. You argued in front of Lucienne, Matthew, Mervyn, and Fiddler's Green with him. As he tried to talk some sense into you, to get you to leave so he could at least rest assured knowing you were out of danger, you noticed his voice shaking more and more and his eyes filling with tears. Here was the reality: the stoic, emotionless king was falling apart.
And you gave in. You stopped fighting to wrap your arms around him. After a moment in which he was surprised, he buried his face in your neck before sobbing. Once, twice, three times. By the time he realized it, he'd lost control and started crying in front of everyone.
The others exchanged glances, not really knowing what to do. They'd never seen Morpheus so... Vulnerable. So broken.
Dream clung to you, trembling slightly. His legs buckled, failing from the exhaustion of his body. He fell to the floor, kneeling with you in his arms, burying his face in your shoulder in a desperate attempt to hide.
His sobs, though filled with pain and anguish, were so weak. As if he was afraid someone would hear his weakness.
The reality was that he would be gone very soon. Forever.
