My 24M mate 26M shit himself after a night out. How can I move past it and not make it weird?

Hi 24M here. I was out with some friends (4 guys, 24-27, and one of their girlfriends, 25F). We were celebrating one of the guy’s birthdays so we ended up hopping from pub to pub and ended up at a club by the end of the night. Everyone was definitely wasted by the end of the night but I lowkey have a fear of throwing up, so I always watch what and how much I’m drinking. All the other guys drank a lot.

One of my friends 26M went downhill super fast. He ended up throwing up everywhere outside the club. We started getting attention from people passing by, who tried to start helping. I was one of the most sober people in the group, so I was running back and forth to get him water and towels. I had to immediately put my vomit fears aside to help him, but I was covered in it. The club ends up telling us we have to leave, he can’t be throwing up like that in front of their business. But at that point my mate was on the floor. He couldn’t move any part of his body. We had to carry him to the car lot before the club called the police.

By the time we get him to the lot, he demands we put him down on the floor or just leave him there. We weren’t able to get a taxi but we managed to get a hold of his girlfriend to come pick us up. When she got there, we picked him up to put him in the car and then he shat himself. It was warm and liquidy and it got all over me and my other mate. We had to put him down and he just laid there shitting himself. He couldn’t stop. We had never seen that happen, and some of my friends are borderline alcoholics, so we decided to take him to the hospital. We loaded him into the car and got him there and he was fine. Everyone was gagging the whole way there. His girlfriend told us to go home, so we all left the hospital. I went home and sat on the floor in my shower for maybe an hour.

Now I’m having this problem where I keep replaying the moment he shit himself in my head. I know it’s not his fault, and I don’t want to accidentally hold it against him in my head. I don’t do well with bodily fluids of any kind, so poop would be the worst for me. I feel like I can still smell it, even though I shouldn’t be able to. How am I supposed to move on from this and act normal? I don’t want to make him feel uncomfortable or like I’m not here for him but I honestly don’t know how I can ever see him the same way again. We’re also coworkers, so avoiding him isn’t an option. He’s now acting like nothing happened. I feel like a horrible person for thinking this way about it.

For extra info, I’ve never seen him or anyone get that drunk before. I get that shit happens (haha) but I really don’t know how common this is. I don’t know if I should also just act like nothing happened or if it’s something that requires addressing. He has a tendency to not be aware of the way he comes off, especially at work. Like he’ll do half assed work sometimes and then talk about how he thinks he’s guaranteed a promotion. I don’t know if this is translating now into other parts of his life. Maybe I am reading into it too much, but I’m just concerned for him and unsure about the best way to go about dealing with this. His girlfriend likely won’t ever address this with him, she’s not confrontational at all and puts him on a pedestal. She plays housewife while pretty much supporting him entirely financially, so there’s not much hope she’ll say anything to him. Don’t know if he should hear from his mates about how we’re concerned for him or if we should just drop it. Any advice would be great thanks.
