The Hollow Shadow: Is SCP-650 the Original Vessel of SCP-035?

I’ve been diving deep into the "Main Canon" of SCP-049 and SCP-035, specifically the lore established by Gabriel Jade. While the connection between the Doctor and the Mask is iconic (rooted in their Alagadda past), there’s always been a frustrating gap: Why does 035 dissolve every host? And what did he look like before becoming just a mask?

I have a theory that might sound a bit "funny" at first, but the more you look at the lore, the more it makes sense: SCP-650 (The Startle Statue) is the original, hollowed-out body of SCP-035.

The Evidence:

1. The Perfect Puzzle: SCP-650 is a featureless, black humanoid statue with no face. SCP-035 is a highly expressive face with no body. They are literally two halves of a whole.
2. The Alagadda Connection: In the Alagadda lore, denizens are often described as masked shadows. 650’s black, anomalous material matches the aesthetic of a high-ranking Alagaddan entity that has been "emptied."
3. The Corrosive Fluid Paradox: 035’s fluid destroys all organic matter. Why? Perhaps because it is "mourning" its original form. If 650 is the original vessel—made of that strange, indestructible anomalous material—it explains why 035 rejects every other human host. Nothing "fits" quite like the statue.
4. The Behavior: 650’s only instinct is to appear behind people and startle them. It feels like a "muscle memory" of a creature that used to be a terrifying, sentient manipulator (035) but lost its consciousness/face.

The 049 Angle:
Gabriel Jade’s SCP-049 is obsessed with "perfection" and "curing" the pestilence of death. If 049 knew that his old friend (035) was separated from his true, immortal vessel (650), his ultimate "cure" wouldn't be for humanity—it would be a surgical reunion of the Mask and the Statue.

Conclusion:
035 isn't just a cursed mask; he’s a "lost soul" looking for his specific, anomalous shadow. 650 is the silent, mindless "shell" left behind.

What do you guys think? Does this bridge the gap in the 035/049 Alagadda lore, or am I reaching too far into the darkness?
