Through Paula's drawing, Hector recognizes a frightening symbol in the school emblem hidden in plain sight, connects it to significant dates, fathoms how he's been used, and fears human experiments have not stopped. A bruise on Elsa's cheek convinces all that Jacques has shown his true colors to her at last. Elsewhere, Ivan realizes he's being abducted, Lucia gives Hector the cold shoulder, Fermin engages in a joint effort to capture a war criminal, Marcos threatens a teacher, Hector finds a disturbing photograph tucked in a dedicated first edition, the teens engage in a Nacho expedition, Hugo solves a problem named Maria, and Paula takes Ivan's advice and locks up Julia to await a lobotomy.
