The scene opens with Lightman going through an office building of the social network application “Seekout”. He is taking pictures. He talks to Zach Morstein, the owner of the application and asks why he fired Kyle Punam, a co-founder of “Seekout” before the company went public and make billions of dollars. Zach tells that Claire, the third co-founder of the application, must have hired Lightman and tells that he and Claire are friends. Zach tells Lightman to tell Claire that she’s safe. Lightman and Foster meet Claire and Lightman tells that Zach’s smile worries him and tells that Claire is going to get fired too. Claire tells that Zach has changed. However, she tells that they are still friends and that she is not going to fight him. Lightman starts to wonder if the “change” is more than business. Claire tells that she has to leave and doesn’t say anything further...
