I was thinking the flowers was more of the new colors they had. Maybe they didn't show that one at the end since they never really got to talk so he wouldn't be able to point out the personality/ reaction like he did with the others. Also about the flowers it's their hair color so it makes sence for 11 different colored flowers to show up. He died with his regular a color so I true smart brown as the hyung with short hair.unlessput two sets of the same brown flowers. There were also quite a few white bundles so maybe one of those could have been his. Most of the coors had found flowers but the white one. I just feel that if all the others that died where brought back than that one should have too.
There were 12 hyungs in the beggining and only 11 different coloured flowers on the blanket, so I'm guessing the first hyung that said he hated Doyoung and that Doyoung straight up called a fake didn't make it, not to mention he didnt show up in the epilogue
