(via phone while Gideon is at the florist)
Hotchner: Jason?
Gideon: Yeah?
Hotchner: Button mums are something you give your mother. (edit) Hotchner: My team? Let me tell you about my team. Agent Morgan fought to protect his identity from the very people who could save him. Why? Because trust has to be earned, and there are very few people he truly trusts. Reid’s intellect is a shield which protects him from his emotions and, at the moment, his shield is under repair. Prentiss overcompensates because she doesn’t yet feel she’s a part of the team. She needn’t worry. Every day, Agent Jareau fields dozens of requests for our team and every night she goes home hoping she’s made the right choices. Garcia fills her office with figurines and color to remind herself to smile as the horror fills her screens and Agent Gideon in many ways is damned by his profound knowledge of others, which is why he shares so little of himself yet he pours his heart into every case we handle. I stand by my actions and I stand by my team, and if you think that you can find a better person for the job, good luck. (edit) (to the florist)
Gideon: Do you have a yellow flower? They’re like, uh, they’re little yellow flowers… They look like dandelions, or like weeds – but they’re not weeds… They have a little black spot in the middle, but they don’t have a black spot… They’re sort of round and puffy?
Sammy: Button mums.
Gideon: Do you have those? Can I see what those are? (edit) JJ: No matter what happens this time, we don't split up. Clear?
Reid: Crystal clear. (edit) Garcia: (imagining the headlines while waiting in her car for Gideon) Gorgeous tech kitten found in lonely, dark parking lot, throat slashed ear-to-ear. Horrific. Tragic. With the very files of one of the most prolific serial killers ever. Tonight he remains at large, the blood of Quantico’s finest… (edit)

Garcia has to plot out the ages of Frank's kills for Gideon. When she reads them out loud, she begins, "He killed 43 in their fifties..." However, at the moment Garcia says "43," that information had not yet appeared on her screen. (edit) Rebecca Bryant, the victim saved in "The Fisher King Part 2," returns in this episode. However, she is killed by Frank, which makes her the first person to be saved in one episode and murdered in a subsequent one. (edit) This episode introduced Section Chief Erin Strauss. (edit) Garcia is wearing a black wig in this episode when she returns from her date. (edit) Frank and Jane are hit by a fast-moving train at Union Station. Amtrak changes locomotives at Union Station, and the trains run north on electric engines and south on diesel engines. Therefore, a train would not be traveling through the station at such a high speed. (edit)
