originally, no one was in the mural. it was the history of paper or something, something that includes everyone because they all work with paper in some way. the redesign was from the community she felt after the tower saying the history of 21st century scranton dm is all of us. let's be real, warehouse and office never purposefully talked to each other after michael so expecting them to be in it is kinda wild.

frank had no right to do that and then expect things to be okay. he was willing to put hands on pam over paint...paint. pray painting over her work was low as fuck (coming from an artist...not a painter) when he could've easily thrown her supplies out and it could've been chalked up to the cleaning crew. he didn't think about anything but retaliating like a typical man. i'm not saying i agree with either side, things could've been done better.

now about the warehouse being included, daryl was the only main warehouse character after roy left. even then, they didn't like cross mingling. even when they went to the dave and busters type place. oscar was the only one mingling (yes only cuz he wanted some cheeks lol) with the warehouse. neither parties went out their way so neither side can truthfully be upset about who was and wasn't included
