Even if she didn't have any sexual contact with him, the fact she provably spoke to him multiple times via phone shows she's not suitable to work with kids - yes, be chatty and cordial to those without friends, let them eat lunch in the class if you're in there and they're lonely etc, but to think of them as actual friends is just weird. Even if she's found 'innocent' she should be barred from working with children, in my opinion.
I think she's guilty as hell, and manipulated a vulnerable child.
