S2·E21 Into the Abyss

Prince Adam finds his work as He-Man is tiring him out, and Teela is getting frustrated with Adam's apparent laziness, unaware of the real reason for it. After a heated argument between the two of them, Teela decides to make up for it by making Adam train in a fun way, by following her across an obstacle course with a tracking device. Teela runs way ahead of Adam, but runs headfirst into danger as she slips over the edge of Castle Grayskull's abyss and falls down into its bottomless depths. When they realise the possibly fatal situation Teela is in, Adam (as He-Man), Man-At-Arms and The Sorceress must do their best to rescue her before it's too late.
