I also wonder if it was a deliberate choice or just composition, but if you haven't notice, Horus is the only one who doesn't touch Seth directly. Everyone else gropes Seth yet he's only touching the 'hat'.
Hat? You mean the abdomen? His hand in in the middle.
I mean the headpiece, I honestly don't know the english word for it.
I can't say for sure, (especially since the author loves to use the type of lighting that changes everything) but I was pretty sure that the other god (the greek god as some people called him, nameless one, new guy) had a bit lighter skin tone than Horus.
That's why I thought that the top pair of hands belong to Anubis, middle ones (touching only the headpiece) would be Horus, green ones obviously Osiris and that bottom single hand the new guy.
I may be wrong, tho. Just speculating since it's all we get while waiting for new chapters :)
Horus’ hand is in the bottom center, on Seth’s abdomen
I just noticed that there are actually 7 hands. I thought it was weird that Greek God's hand was missing, but nope it's there, I'm just blind apparently.
