I think it will come up but logically how much of a lead is it really? She already knew Batista was investigating Harrison and Dexter. They wont be able to prove the calls came after his death. Its not that crazy that he may have happened to call Harrison before he died. It doesnt prove any wrong doing by Harrison or Dexter. It might feed into suspicions, but Im sure Claudette is going to play a role in season 2 either way with regards to Dexter and Harrison.
