Matthias didn't have to have said the words 'I love you' to him. He didn't because he'd said them by agreeing to have only Sam as his. Sam felt his heart beat faster as a moment he never thought would happen, well, did. This demon loved him and wanted to be with only him.

It was enough for Sam to dive forward to kiss Matthias for the first time. To really kiss him. Oh he'd given him affection in the past but never anything like this. Nothing with all of his feelings pouring out to offer to the demon.

God but he did love him. And his heart soared knowing that he was actually loved back.
