We definitely know that Ella doesn't care if her "Chosen One" is smart or strong (a strong one is better), we know this because Deryl was immediately denied the title, despite, potentially, being able to prove his strength in combat against us and Jake, and being the smartest guy we know. As such it is safe to say that Ella cares about her chosen having a special type of power, or at least being able to develop it down the line with evolution.
The opinion that the special ability is stealing memories and others powers is just dumb, the only reason it is even considered a possibility is because of a power fantasy.
Of the four potential "Chosen Ones" the only thing they had in common, that i noticed, was the affinity to telepathy.
- The two jocks were both sons of the big tidy snake lady, who we know can use it to communicate with her minions, and to speak to us during the "Fight of the Titans".
- Jake can literally control others minds, it is not that big of a stretch that he will learn how to speak to them that way (probably his 3rd evo, since it would mean he no longer gets fucked by people in headphones).
- MC might not have telepathy per se, but mind reading can be used as a shitty one way laggy form of it (someone thinks something, MC reads the latest memory and hears the thought).
This leaves the question of why the fuck does Ella care, and why can't she just use the Miniyak or any other monster for the job. The reason monsters don't fit might be because none of them would do the thing she wants (might be considered heresy to them), or because all of the telepaths are members of the faction that is hostile towards her. The reason she cares, is that she wants someone to talk to the stone creature that she is collecting, it might be that that thing is one of the gods and she wants an audience with it, or because there is some form of monster "Collective (un)conscious" that she wants to enter (I think that whole meeting with the First one after we kill Jake was inside of one).
