Empty Promise

The situation is dire, maybe even hopeless, and everyone is losing hope faced with certain death. The Chick or The Hero have to keep their friends and loved ones not just moving but hopeful in order to survive. So they lie. They hold their loved ones close and say "It's going to be all right", or "Help is coming." The loved one may very well know it's an empty promise, but needs and wants to believe it, because the alternative is panic or an emotional breakdown.

If the situation truly is hopeless, expect them to say "close your eyes", possibly even killing them to make sure it's a painless death. If the loved one truly has no idea of what's going on, and is on the point of death, it becomes Let Them Die Happy. Expect the hero to cradle their friend as their doom approaches.

Television

 * In 'Reboot', this trope is subverted. When Enzo appears to be losing a game against the user, Andrala promises Frisket everything will be ok, and resets their icons. When the game cube vanishes, it appears as though Andrala had made an empty promise, which is partly true; by resetting their icons to game sprite mode, she ensured the three of them would live even if they lost the game, but they wouldn't be able to return to Mainframe.

Film

 * In The Dark Knight, Harvey Dent promises to Rachel that
 * Rachel had also promised Bruce that she would wait for him.
 * Not so much an empty promise as a Broken Promise.
 * In the original 1954 Godzilla film—which was a lot more serious than its camp successors—the mother of a family trapped in the monster's path soothes her children with the promise that they would be with their father soon. No prize for guessing their father's status.
 * Dr. Loomis to Jamie, in the school, in Halloween 4. Subverted when she asks him if he really believes they'll make it out all right, and he gives a barely audible Little No.

Live Action TV

 * This happened in an episode of House, where the son got sick because of radioactive scrap metal. The team was able to help him a little, but he still had cancer and no immune system with which to fight it. The father still told him everything was going to be all right, even though the son was dying and there wasn't anything the doctors could do about it. Also happens on the episode "Euphoria", between and his dad, although  called him on it.
 * Happens a lot on Law and Order, when the police tell a witness that they can protect him or (usually) her. The amount of reassurance the police give a witness is directly proportional to the odds they'll end up getting kidnapped or killed later. Cue "I told her it would all be okay!"
 * Pretty much happens every other episode in Twenty Four, with Jack promising to get someone out of an impossible situation. It usually doesn't work out.
 * Helo from the new Battlestar Galactica Reimagined loves this one, although other characters do their fair share as well.
 * On Mad Men, it was Don's repeated empty assurances to Betty that everything would be all right after Kennedy was assassinated that finally drove her to end their marriage once and for all.
 * In the series finale of Angel Illyria shapeshifts into Fred and comforts Wesley in this fashion as he dies, telling him in particular that they'll be together afterward. However, Illyria consumed Fred's soul during the resurrection process.
 * It's implied by Illyria's changing attitudes and uncomfortable emotions that at least a fraction of Fred's soul survived, though it may have incorporated itself with Illyria's demonic essence. However, whatever may remain of it is certainly not waiting for him in the afterlife. That's okay, Wesley isn't moving on either.
 * An episode of Criminal Minds had Hotch questioning the only witness to an arson, a woman who'd lost her husband and son in the same fire, and at the end reassuring her they were both waiting for her outside. He'd been specifically told by the doctor he could tell her whatever he wanted because she'd not live long enough to know any different.
 * In Haven Audrey will often tell someone that things will be OK as she tries to fix whatever damage the episode's Troubled person has caused. When  is about to die she can't do anything to help him and says nothing. This infuriates Nathan who preferred that she at least gave an Empty Promise to comfort
 * Buffy the Vampire Slayer. The "close your eyes" version happens in the Season 2 finale. Angel's soul has been restored, but Buffy can see over his shoulder the vortex that's about to pull them into the hell dimension. She kisses Angel and then runs him through with a sword, sealing the rift.

Western Animation

 * Robot Chicken uses it in a horrifically bleak, though still funny, Black Comedy way, as Voltron's Combining Mecha sequence is taking so long that the enemy's destroying the space station that'd called for help in the meantime. The general's young sidekick is dying in the wreckage, blind and crippled from his injuries, and asks if Voltron's arrived. The general lies and tells him yes, Voltron's here and it's all going to be okay now, before shooting him so he'll die painlessly.
