Assuming its not a modded version of Kik (and there are loads out there), get her to send a "live pic", with something scribbled onto a piece of paper so you have a reasonable chance of it being the person you're speaking to.
Are any of the pics "she" has sent you been "live pics", was the link to "protect her" a url with just IP addresses, did she find you - these are all hallmarks of a kik scam
