Work Text:
Robby had sustained severe injuries while he was with Cobra Kai. He knew they were severe. He knew that he should tell his father about it, but he was afraid that showing any sort of physical weakness would break their budding relationship.
Anyone could tell that he was hurt. The bruises and scratches all over his body made that obvious enough. But Robby had sustained less superficial internal injuries as well. And these are outside of the serious uptick in the amount of anxiety that Robby felt or the suicidal thoughts that hadn’t fully left him. He had serious physical internal injuries that no one really knew about.
Hell, Robby himself only knew about it because of the blood.
One day while Johnny was at work, Robby started feeling like he might be sick. He went into the bathroom and kneeled over the toilet, feeling as if he might vomit. Then his throat began to itch and his body responded by coughing, hard. This caused the boy to enter a coughing fit the likes that he had never seen or experienced before.
Robby was surprised when, as he was coughing, he felt his mouth fill up with something. Something that tasted kind of coppery. He knew before he even spat that it was blood.
Seeing the blood that he had coughed up swirling in the toilet water was the last straw for Robby’s anxious stomach. He threw up into the toilet bowl. When he glanced down, he was surprised, and a bit fearful, to see that more blood had been added to the mixture.
He flushed the toilet quickly in order to avoid looking at the mixture anymore.
The thought that he was coughing up and vomiting blood scared Robby, but he tried to think about it logically. He had never coughed blood before, especially not since staying with his dad and dropping Cobra Kai. This was the first time that something like this had happened. And he didn’t feel like coughing anymore, so maybe it was only going to happen this one time.
In the end, Robby decided not to tell his father about the whole “coughing up blood” situation. After all, Robby had convinced himself that he was probably fine and if he was fine, then it was nothing to worry his father about.
Little did he know that it would only get worse.
