From yesterday’s episode we learned that Tara has left the life that she knew behind her, first when she got her head blown off and secondly when Sookie convinced Pam to turn Tara in a desperate attempt to save her “life”. Tara is not Pam’s first progeny however as she mentions before going to ground in Sookie’s backyard.
From the season 2 Blu-Ray we learn who Pam’s first progeny was. His name was Colin.
