Based on Olivia's appearance at the latest Spaulding board meeting, Alan suggests Gus take a step back. Gus assumes his father is trying to get rid of him and becomes defensive. Alan wants to protect him from the evil Olivia is capable of and he feels guilty for taking him away from his police work. Gus wonders if this sudden change of heart is because he may be getting too close to discovering possible flaws in the company - he mentioned Antimonious at the meeting and Brad's Russian fax. Gus reminds Alan that he can be trusted and that if his father is in trouble, he can help. Alan sternly insists Gus "drop it" before abruptly getting up from their table. He apologizes for snapping; he's been under a lot of stress. Gus knows he hit a nerve and wants Alan to talk about what's bothering him. He refuses just as Buzz, Billy and Josh enter from the kitchen. Gus eyes them curiously. After Gus leaves, the guys tell Alan they found nothing. Josh says it's time to play offense. They have to get the girls away from this witness and then somehow draw him/her out. Josh reinforces the fact that they must all watch each other's' backs - even Ed's.
