Others update #2 (Patreon)

Check out the passage immediately after Sam stabs an Other with a dragonglass dagger:

"When he opened his eyes the Other’s armor was running down its legs in rivulets as pale blue blood hissed and steamed around the black dragonglass dagger in its throat. It reached down with two bone-white hands to pull out the knife, but where its fingers touched the obsidian they smoked.

Sam rolled onto his side, eyes wide as the Other shrank and puddled, dissolving away. In twenty heartbeats its flesh was gone, swirling away in a fine white mist. Beneath were bones like milkglass, pale and shiny, and they were melting too." (Samwell I, ASOS)

So Others have "blood", "flesh" and "bone", like natural, biological creatures – which kinda conflicts with the idea that Others are supernatural "Demons made of snow and ice and cold" (Stannis Baratheon, in Samwell V, ASOS).

Maybe Others are more like humans than they seem...
