Is That Her?!

so I was going through these screenshots of ROTG (which can be found in high quality at Disneyscreencaps.com) and I saw this one...that girl, standing over to the left talking to the man that looks like a preacher. doesnt he? or something like that?!

is that girl Jack's sister and he didnt remember her until it was too late... OMG FEELS.

also, the boy that runs through him in this scene, looks like his sister's friend when Jack looks at his memories...!!!!

I own nothing, just a theory.
