did kathy or phil say when they made contact with each other

Kathy emailed Phil when she heard Ben had been convicted of Heather's manslaughter, so it was several years ago. I think the evening of the live episode was the first time they met in person.

I just remembered; when Sharon first went to that solicitor to ask about who her birth father really was, the solicitor mentioned about hearing someone with the name 'Gavin'. Sharon and...Ian, was it? went to see Dot in prison, to ask if she knew anyone with that name.

Yes, it's a very popular fan theory that Gavin is Sharon's biological father, and the writers seem to be hinting at it with Sharon's remark about Ian being like a brother to her (they'll be step-siblings if she is Gavin's daughter).
