Eugene Coyle walks up to the team and Tony tells him the only witness is his father.

Ducky investigates the body with Jimmy. Gibbs says the time of death corresponds with when Bodeen left the hotel. Bishop offers to bag the pillow and Tim makes her pick up all of the feathers.
Tim debriefs the team on Michael Elliot, their latest victim. He works for Senator Denise O'Hara. Bishop says he must have let Bodeen into his hotel room. She telsl Gibbs that Tony's out looking for his father.
Abby lets Coyle into her lab and shows him evidence that shows Tony was right ni shooting Bodeen. She has evidence that Elliot was killed by the same gun that Bodeen had on him.
Tim enters Bodeen's offices and takes out his gun when he hears noises in the next room. When he enters he finds Tony at Bodeen's desk. Tony uses one of the keys Tim has to open the only door he couldn't get through. Inside the back room is surveillance equipment and Tim thinks it is what was used to hack the hotel security.
Bishop and Gibbs enter the conference room to see Navy Commander Lionel Saxon. Saxon received a call from Elliot on Friday and suggested they meet at a hotel room. He had trouble getting inside and when he did the room was locked with a busy sign. Saxon asks if Bodeen was impersonating him and Gibbs stosp to consider that.

Tony meets Anthony in the hotel bar. He's been staying at the hotel with a friend but won't say anything else yet. Anthony worries about how much danger Tony is in. The news he wanted to tell Tony is that he's getting married.
Bishop fills Tim in on the connection between Elliot and Saxon. Tony walks up and explains what his father has been up to. He doesn't know anything about his future step mom and asks what Bishop knows when he sees her face. Tim makes a quick escape to avoid any talk about Anthony. Bishop tells Tony about the pregnant woman they saw after he threatens her.
In Abby's lab, she works to break into the safe found in Bodeen's office. Tim helps her open it and inside they find a gun, a phone and cash from Macao. He discusses this with Gibbs and they agree it's the gambling capitol of the world. Tony walks in ignoring a call from his father. He says Bodeen has been to Macao and Gibbs asks how he knows about Bodeen. Tony blames Tim's photos and asks him to bring them back up.

At the office, Tim tells Gibbs that Bodeen has made 17 calls to a phone registered to O'Hara. Bishop says Calvin Ling lives in Macao and owns a company that supplies American navy vessels in Asian ports of call. O'Hara's committee is working to eliminate some of those ports of call. Tim suggests that Elliot was killed when he discovered that O'Hara took a bribe from Ling.
Abby plays a recording of Elliot speaking to Saxon. He sounded paranoid and Gibbs thinks that Bodeen had listened in on their conversation. That's how he was able to kill him before Saxon arrived.
