Leon was not known to get a long with people, he was cold and to himself, so for you to get through him and dating him it was a shocker. Ever since he always kept you safe on missions, made you stay home when you was sick, everything to keep you safe.

One mission during a zombie apocalypse you two separated to find the person that created this virus, but then you entered one house hearing groans and sounds of screaming

You walked into the room seeing leon and way more veins than he usally have a hole bunch looking like a vine of a tree all black realizing that he got bit and it was real bad on his face

"leave.. before i do something stupid.."
