Remember this post?
I’d like you to notice something, which further enforces the headcanon that Russia has heavy scarring on his neck from The Golden Horde, which he covers with his neck.
In the red insert, you can clearly see BANDAGES wrapped around his neck. Bandages. Around his neck.
So if that doesn’t prove the scars headcanon to you, I don’t know what does. In other official art, he has a scarf or a high collar on. Always.
