Familiar Faces.
Tina hadn't seen Cassidy since she lost consciousness in the Blackbird on the way home after Fargo and to say that it was a less-than-good way to see someone last was an understatement.  It was made worse by Jake's death and while Tina was internally grieving that pretty hard---Jake had been one of her few friends--she knew Cassidy had to be going out of his mind.  He had not gotten off on a good foot.  Now that she was leaving for a mission, she knew she couldn't just go away for a bit without seeing him so after she met with Scott, Tina decided to track him down.
