Hey there, it's been a while since you commented so I'm sure you've probably moved on from this, or have found the other paths yourself, but if you're still wondering about the other two trait endings,
bit of a spoiler warning:

once you exit the room you awaken in, ignore the bugs itching at your legs, and it will lead you to a new trait
as for the remaining trait, just go back to the glass you smashed in the room with the cased insects, and give it another inspection. this should lead you to the final trait
that's about it, hope this helps anyone else who may be wondering about the same thing. :)
