USA TODAY Contestants on "The Bachelorette" this summer have shown greater comradery than in seasons past, but that didn't stop tension from mounting with the arrival of franchise alum Blake. Monday night's episode saw the official entrance of the man who dated "Bachelorette" stars Clare and Tayshia last season, much to the worry of current star Katie's existing suitors, many of whom are beginning to develop real feelings. Greg, who received Katie's first impression rose, says he feels like he's "dating Katie at this point" and is struggling to come to terms with new person coming in. Naturally, this triggers an immediate 1-on-1 date card for Blake.
