That is the photo he got. Everyone got a photo like this, one person is not on it, to make it look like the others were knowing eachother the whole time.
If you look at it reversed, you can see how happy everyone is: Hifumi taking pictures of the donuts while Sakura tries to pick him up by the hair Sayaka and Aoi just eating donuts Leon jamming out Mondo sleeping Mukuro looking like she’s attached to Mondo Chihiro and Makoto just being pure cinnamon rolls Syo obsessing over Byakuya Celeste and Kyoko creepily staring into your souls And then you get to the next half.
I don’t. Know if anyone else noticed this but, Looking out the window is The Ultimate Fashionista, you can tell by the big red spot. But, if you noticed, next to Mondo, (the one with the head on the desk) is Mukuro Ikusaba.
