Melissa & Sam
Dean's recent death and return home or whatever was a subject Sam did not care to discuss with anyone, not even Dean himself. He drew a breath, shrugged it off, and nodded. he knew Melissa meant well, didn't mean to upset him. He wasn't going to get upset. he was just going to let it go.
"Yeah. That was rough. For all of us. But it's all good now." And that was all he was going to say on the matter. "You and Tea have known each other a long time, haven't you?"
