He knew better than to push.
Pushing never got anything other than the iron-tight lock down of his shutters, but the pain, grief, loss oozing from his brother was so hard to take.
"Please, Dean..!"
It was a plea.
He watched the familiar muscle tick as his jaw ground against the anguished scream it held back. His green eyes brimmed with soft, sad tears and his lips whispered the words.
"I miss her, Sam..."
He dropped to his knees on the muddy grass, and Sam was there to grab him as he collapsed, sobbing into his brother's safe, strong arms.
