how to get all ending!
I've been compiling images of My Clem profiles over in the My Clem Compilation thread and, after looking at what I've got so far, I think I've determined what affects Clem's decision to either stay with Javi or make her own decision.
It would seem that your Season 2 ending locks you into a set number of Your Clem profiles. From there, your decisions during the Clem flashbacks have the final say. Judging from the flavour text, the three key decision points that determine your Clem are:

Accepting or Rejecting Ava's Offer
Injecting AJ or Obeying the Rules
Saying Goodbye to AJ or Spitting on David

If you accept Ava's offer and inject AJ, your Clem will be loyal and she will follow Javi's lead.
If you accept Ava's offer and obey them with AJ, your Clem will be understanding and will go after Gabe.
If you reject Ava's offer and inject AJ, your Clem will be levelheaded and will go wherever Javi doesn't.
If you reject Ava's offer and obey them with AJ, your Clem will be forgiving and will, again, go after Gabe.
If you reject Ava's offer, inject AJ and spit in David's face, your Clem will be cold and will go with Kate.
If you reject Ava's offer, obey them with AJ and spit in David's face, your Clem will be honest and will, again, go wherever Javi doesn't.
If you accept Ava's offer, inject AJ and spit in David's face, your Clem will be bold and will, again, follow Javi's lead.
If you accept Ava's offer, obey them with AJ and spit in David's face, your Clem will be just and will, again, go with Kate.

As such, it would appear that our Season 2 endings have less say in the Season 3 ending than it would initially seem in that they only really influence which set of Your Clem profiles you'll have access to. In theory, there are four distinct routes with eight unique profiles which can be unlocked depending on your choices, meaning that there are 32 Your Clem screens out there waiting to be unlocked.
