From top to bottom:

1: When Nathan was alive, Abaddon would sometimes run up behind him and help himself to a piggyback ride.

2: Where does all of that hair come from...?

Other page/next section:

I'll add things here & there since I was running out of room on paper to write what I wanted to write.

1: Boy why do you grow distant?

2: Nathan and the ghosts kept petting him.

The informational segment on Abaddon:

Abaddon isn't very good at fighting, so he relies on defense and escape/hiding. ○ One thing that helps him to escape and hide is being able to "hide" in shadows. - Think The Collector (The Owl House), or Prismo (Adventure Time). ○ However, while he can "shift" into these shadows, if he is injured he cannot heal or defend himself. ○ He cannot be "touched" (To others it might just feel like the floor or the wall, he'll typically move out of the way as he still can still somewhat feel the sensation), but he can still be impacted by outside factors. - Ex. if someone were to splash water onto him & he were to exit from the shadow, he would be wet.
