Charlie walks in Don's apartment to find the lights dimmed and his brother covered with a blanket. He blinks, confused. "Aren't you warm wearing that?" he asks, moving carefully through the apartment so he doesn't trip over something.
"Actually, the opposite, Charlie," Don replies, a cough racking through his body before he pulls the cotton closer to his body. "Thanks for giving me your cold you had last week, by the way. Really appreciate that."
"Oh. I thought you didn't get sick." Charlie grins and chuckles. "That's what you told me when I protested after you kissed me, anyway."
"What, I'm not allowed to be wrong?"
"No, you are." The younger Eppes feels concern worming its way through his system as he sits on the end of the couch and places his hand against his brother's forehead. "You're burning up."
"Gee, I never knew that," Don mutters, annoyed. "How did you find that out, genius?"
Charlie shakes his head in fond amusement. Don was always a little bitter and irritable when he was sick. "I don't know, maybe I did some calculations when you weren't looking."
The agent cracks a smile at that. "Don't start on me. My head is already swimming."
"Sir yes sir."
Charlie gets up, seeing Don shiver even though he was covered with a heavy blanket. He goes towards the closet, pulling out another one and covering his brother with it. "Need anything else?"
"Having you around is a pretty damn good cure-all, buddy." Don throws a lopsided grin in Charlie's general direction before his eyes flutter. "Do you... have anywhere to be?"
"I can stay," Charlie says in reassurance, hearing the unspoken question. He presses a kiss against Don's forehead. "Get some sleep."
"Thanks, Chuck," is all his brother says before his eyes fully close.
