So you know that Ella is the young robot version of Charlie,

speaking of that,Charlie's older adult version is a slender circus baby,and who does that sound like?

*cough,cough* Eleanor*cough cough*

I think that Eleanor is an alternative version of adult version of Charlie and she chooses to go by Eleanor because of Ella being similar and stuff.

I also think this confirms my previous Ella theory about her using illusion disks is right(altho I'm pretty sure it already was)
