At the end of this episode, Sharkey tackles Weber as the grenade goes off. There's a camera shaking explosion with lots of sound and loud music. Yet, minutes later, Sharkey is lying in bed with his hands clasped behind his head. And Sharkey does not generally appear in any episodes following (aside from stock footage). The reason for this is that Sharkey was originally killed at the end of this episode. Terry Becker and Irwin Allen had a dispute over salary and Becker left the show. However, Irwin could not find a suitable replacement for him and, after coming to terms, re-hired Becker. The final scene was hastily written and shot to show that Sharkey was merely "kinda busted up" and that Weber took the full force of the explosion.
