"The Bonding" is the fifth episode of the third season of the syndicated American science fiction television series Star Trek: The Next Generation, the 53rd episode overall, first broadcast on October 23, 1989.

Set in the 24th century, the series follows the adventures of the crew of the Federation starship USS Enterprise-D. In this episode, an Enterprise crewmember is killed in a tragic accident, leaving a newly orphaned young son to deal with her death.

While investigating a planet once occupied by Koinonians, Security Chief Worf and members of the Enterprise away team trigger an ancient mine. They are transported to Sickbay, but Lieutenant Marla Aster is dead. As Captain Picard delivers the news of Marla's death to her son Jeremy, Wesley Crusher talks with Commander Riker about how Picard had delivered the news of his father's death to his mother and himself. Worf expresses his desire to make R'uustai, a Klingon bonding ritual with Jeremy, as they are both orphans and he believes he can help the boy recover emotionally, but Jeremy blames Worf for his mother's death.

The crew investigates the planet, discovering mines that were recently unearthed and exposed. They observe a beam of charged particles emanating from the surface headed towards the Enterprise, while Counselor Troi senses a new presence from the planet. In Jeremy's quarters, a physical manifestation of Marla appears, explaining that the crew mistakenly considered her dead and that she wants Jeremy to live on the planet. Troi and security follow the two preventing "Marla" from using the transporter to return to the planet. They return to Jeremy's quarters, which has the appearance of the Asters' home on Earth. Chief Engineer La Forge tunes the shields to stop the particle beam, causing "Marla" to disappear and the room returns to normal.
