โIโm going to take care of you, okay?โ - from Cat
There was only one person in the whole entire world that Eddie allowed himself to be vulnerable with - and that was Cat. It wasn't an instant thing either. It took a lot to get here. Eddie kept his walls up around her for a year. She was stubborn though. She stuck around and broke through and now she was the only person in Hawkins High that got to see all sides of Eddie Munson.
Including a sick Eddie Munson. As happened every single fucking year with the turn of the seasons, Eddie Munson got the flu. He never told anyone when he got sick. Uncle Wayne knew and he'd call the trailer to check up on Eddie. That was it.
Eddie figured a week home from school wouldn't be so bad. Rest, liquids, ride it out. That was his plan. Worked like a charm every single time. Clearly Cat had other plans. She showed up to the trailer park and just walked into the Munson trailer, scaring the shit out of Eddie in the process.
"God damn it! Do you knock?!" No, she didn't. She hadn't knocked forever now. "You shouldn't be here. I have the plague. Again."
