I STRUGGLED OVER THIS EXPLANATION SO PLEASE I HOPE U LIKE IT

Okay basically we WERE in a flashback inside of a flashback. The first flashback (that this chapter is showing) is showing us this they first met. In the beginning of this arc we see them at their jobs field week or whatever and we see snake and chicken getting along and always bumping into each other. Then on one of the last nights of like job a big commotion happens at the diner and both chicken snake go outside to breathe and end up talking. A this is where the start if the SECOND flashback begins. Chicken and snake are talking about the commotion that happens at the diner (about how people can just turn their backs on u easily, which is what happened to their co-worker which caused the commotion). At this limit snake tells chicken a story about his "friend" [himself] and what happened to him in the snake clan (basically everyone was nice to him bc his grandfather favored him and once something happened they all turned their backs on him and whatnot) and then the second flashback into snakes memories ends. This is where I assume they had a miscommunication and started to dislike each other, because snake said "I hate that ur a goody two shoes" and chicken seems to take that to heart and insukts him back and stœchiométrie off (very cutely I might add). So to clarify a little bit more; this arc started when snake signed chicken up for a "field trip" or something AWAY from the office because there’s rumors about someone sleeping with a boss. (Everyone assumes it’s Ivan but obviously it’s chicken.) so Ivan is trying to protect chicken from the rumors but chicken just knew he signed him up for the trip w/o telling him. From what I remember they were talking about how Ivan doesn’t need to protect chicken; and then they stated reminiscing WHICH LED TO ALL OF THIS

God I hope this made sense because I tried to explain as best I could from memory.
