Marlena has a VOICEOVER for 12153 (8/21/13) in the last act (Act 7-Scene F)

Sami is in jail for 12151 (8/19/13) for the Sami's Jail Cell scenes, which also feature EJ, and Caroline showing up for the last three scenes.
The Sami's Jail Cell scene begins the August 19 episode and features Sami and EJ.
Sami is featured in all 8 acts of 8/19 in Act T-Scene A, Act 1-Scene A, Act 2-Scene C, Act 3-Scene C, Act 4-Scene A, Act 5-Scene B, Act 6-Scene A, and Act 7-Scene.

Those scenes will be Act T-Scene B, Act 1-Scene B, Act 2-Scene B, Act 3-Scene D, Act 4-Scene B and Act 5-Scene C...before the photo cuts off.

i guess Sami's gonna use the gun Kate gave her as a gift...

First the September "casting" and now a spoiler 3.5 months out. This is no fun at all.
