Was I wrong for it, and will we be okay?

So things have been a little rocky with my old work partner for like a month now. The last day we worked 1-on-1 together was incredible, but ended up with him telling kids to draw on me. They did, I said I'd get him back. I slightly sprayed him with a squirt bottle and I tried to hit him with a waterballoon, but I overshot. So this week at work we're doing all kinds of water stuff. Especially today, be ready to get wet. Yesterday, some kids sprayed me with a hose. He thought it was hilarious. I rang my shirt out on him, chase ensued, he threatened to tell a kid on me. Usually he doesn't mind that kinda stuff. Well today, I dumped a mass water bottle out on him. He didn't seem to mind. But the other people around were like what the heck, that was uncalled for. I reminded him about the drawing, and he was like "I never said that." I was like, "you really don't remember that?" He shook his head. I apologized like 50 million times and he said it was all good, someone did dump another water bottle on him later which he said they could, and he got soaked from the activities. He wrang his hair out on someone else. Messing with/scaring people is something he loves doing, but I still feel pretty guilty. He doesn't get me often, just laughs when others do or encourages the kids to do it by either telling them to or laughing. I feel guilty though. He said we're definitely fine, but most of the reason I did it anyway is because things have been rocky and I always overcompensate when that happens. He never makes me feel guilty intentionally, never says anything, it's because of a self-blame thing I have, but the other two people around definitely weren't fans. One of them doesn't like me already, but did I mess up too bad?

It's worth noting that he reacted the same way to the other person who had permission to pour water on him as he did to me.
