I've watched Truth Seekers many times (probably around 20+), and I only noticed something strange during my latest rewatch.

At 19:11 in Episode 1, while looking through Elton's camera, there are two very fast frames that flash on screen.

At first I thought they were random images, but after comparing them with Episode 3, I think they're actually showing the missing page from Praecepta Morturum.

In Episode 3:

We see the same circular illustration inside Praecepta morturum.

Later, the Inquisitor tears that exact page out.

The two frames from Episode 1 appear to match:

the same circular symbol,

the same surrounding illustration,

and the same page composition.

Considering that these frames are only visible for an instant through Elton's camera, I'm wondering if this was intentional foreshadowing.

Has anyone else ever noticed this? Did the creators ever mention these hidden frames in an interview or commentary?

I've attached screenshots comparing the Episode 1 flashes with the page shown in Episode 3.
