Interactions with the player character
|This character has no special interactions.|
If the Sole Survivor fast travels away and back to Diamond City once, they will encounter Kyle, Riley's brother, holding Riley at gunpoint, accusing Riley of being a synth. Either the Sole Survivor or a Diamond City security officer intervenes and saves Riley from being shot.
- The city does not become hostile if the player character intervenes by killing Kyle. If Riley is attacked, however, Kyle is immediately killed and the city becomes hostile.
- Riley does not carry any Institute items nor does he drop a synth component upon death, indicating that he is indeed human, not a synth.
- Following the resolution of the event, one can talk to the Diamond City security officer and pass a Charisma check.
- If Riley survives his encounter with Kyle, he will eventually disappear from the game.
Riley appears only in Fallout 4.
