SHIELD issues a "Code Yellow" to save an old friend. Deke Shaw, future grandson to Fitz and Simmons, has been spending his time in the present utilizing his knowledge of the future and SHIELD tech to create a successful company. This has made him happy and comfortable, but completely unaware that he is the target of Sarge and his band of mercenaries. When the Coulson look-alike shows up at Deke's office, he tries to learn a little from the chatty target. Eventually, even Deke can tell there's something wrong and has to once again run for his life. Back at headquarters, an alien bird that came from another of Sarge's victims, makes Agent Keller an unwilling host as it flies inside his body and takes over. Sacrifices are made as Jay and Josh enjoy their boba on this week's Agents of S.H.I.E.L.D.: Case Files.
