So Glam tests their power some more, and then has a meeting with Piggot where they explain the Siberian. She listens carefully, then asks them not to demonstrate, and says she will communicate that to the appropriate people. That takes a while, and then Lorica is asked to confirm this, and then Glam is asked to demonstrate to very few people with very high clearance.

This should not get out, it would be a PR nightmare, but if the Sibarian copy does what it looks like it does, its help will be invaluable in the upcoming Endbringer fights. When Glam decides to use that power, the story will be that a power copier has grabbed the Siberian's and is using it against the Endbringer, that people should not panic, and that she is an ally. Glam mentions, since they're all being so cooperative about telling everyone on the comms, that the Siberian copy doesn't have to look like the original, so people can know whether to panic or not based on her shape.

That leaves, of course, Glam's own willingness to face the Slaughterhouse Nine. Even if they don't know that Siberian is them, they will likely cause problems, and this will need to be carefully planned.

Careful plans tend not to survive contact with reality, and that is doubly true when the next Endbringer attack happens only two months and nine days after the previous one.

Not that it would matter much: Glam is definitely not going to a Simurgh fight, not yet.
