While him following Iname and Miss Selton is slightly odd given the timing, I still maintain that My Fake-beard being a robotic British agent and appearing at an odd time more likely than SHADE developing both telepathy and power ring scan blocking measures at the same time British agents made their move against Grayven.
Actually, that's kind of confusing. Bullet point lists for "Improbable things that SHADE or Britain would need to do to explain the current events."
If Mr Fake-beard is SHADE:
- SHADE develops telepathy resistance
- SHADE develops something to block power ring scans
- SHADE has an agent tail Iname and Miss Selton at the same time British agents make their first obvious move against Grayven
Why the agent is following the two girls makes sense.
If Mr Fake-beard is British
- Britain has an agent tail Iname and Miss Selton shortly after Miss Selton told off a SHADE agent
Telepathy resistance doesn't need to be explained as they have robots, power ring blocking doesn't need to be explained because Britain works with magic more and they showed power ring blocking magic in the latest update, and the timing makes sense.
While the first option is still possible, the simplest explanation is that Britain made their move at a coincidental time rather than SHADE doing multiple improbable things at once.
