The Recuerdo Coil is a small, round, flat, concentric rings device that causes memories to be extracted with a memory spell. The coil is implanted in the sclera, beneath the cornea.
A Recuerdo Coil was implanted in an eye of everyone who knew Bo: Dyson, Kenzi, Lauren, Trick, Hale, Aife, and Vex; causing all of them to forget her, altering remembrance and matters of importance in their lives that existed prior to the 30 days in which they wore the coil.
- It was not shown in the episode, but it can be deduced that when the memory spell was lifted the Recuerdo Coil disappeared from the eye.
- Recuerdo is Spanish language for the word "memory" (noun) or verbal expression "I remember".
