He-Man and The Masters of the Universe Series 2002- Episode 09 "The Ties That Bind"
During a fight with the Evil Warriors at Castle Grayskull, Teela is heavily injured, and receives an emergency blood transfusion from the Sorceress. As an unintended side-effect, she begins to develop telepathic powers, allowing her to read the thoughts of those around her. Realizing this, Man-At-Arms has Adam avoid Teela so that his identity isn't compromised, and also tries to tell his daughter more about her past, only to be interrupted by the Sorceress. Man-At-Arms confronts the Sorceress in Castle Grayskull, criticizing her refusal to tell Teela that she is her mother, and wondering if she even cares for her at all. Meanwhile, gaining awareness of Teela's powers through her magic, Evil Lyn plants a trap for her and the Masters using a fake telepathic message. Believing that Skeletor's forces will attack from the Sands of Time, Teela leads the Masters out to the desert, only to be ambushed by Beast Man's monsters. He-Man and Man-At-Arms help defeat the monsters, and, guided from another message from the Sorceress, Teela leads the Masters back to Castle Grayskull to defend it from Skeletor. After the battle, Teela tries to get answers from the Sorceress as her powers begin to fade, but is left unsure as to who she really is. Later, Man-At-Arms apologizes to the Sorceress, realizing that she really does love Teela, even if she cannot reveal their connection so soon.
Moral: Man-At-Arms tells the audience that a parent's love for a child is the strongest love imaginable, and that the sacrifices they make for their children are difficult.
