You guys are wanting to much from a chapter of a series that will spawn another 100 something chapters. Calm down.
Also if you really dont understand look at the PV
At 1:05 it's the final fight HOWEVER NOW THERE'S KANEKI SPLIT BETWEEN HIS 2 HALFS(human and ghoul) and yes the 2 main characters in this RE version could be kaneki since at 1:14 the guy on the right shows that he has a dark hair color on the back of his head the MC 1(forgot his name) and ofc the dark haired MC 2 on his left. Then of course the inner ghoul hugging the human. Idk my speculation even though everyone said that MC1 is Kaneki that's been brainwashed I think it's just that he's had his inner ghoul removed and he's now 2 people with his ghoul parts removed and him being a human again.(really hard to explain)
