Meanwhile, Hanna is forced to deal with a situation at home that could really cramp her "It girl" status.

Meanwhile, the Marin financial situation is pushing Ashley to the brink.

  11. 11 - Moments Later

    The mystery and ominous messages continue for best friends Emily Fields, Spencer Hastings, Hanna Marin and Aria Montgomery.

And Spencer must now handle the return of happy newlyweds Melissa (recurring guest star TORREY DeVITTO) and Ian (recurring guest star RYAN MERRIMAN  The Pretender, The Ring Two), even though her suspicions of Ian's ties to Alison grow.
