Scenario
In the climax of the film, Agents J and K confront Edgar, an alien resembling a giant bug. After Edgar swallows J and K's weapons, K declares his intent to get his gun back. As Edgar attempts to leave Earth, K stops him and taunts him while goading him into eating him. Edgar falls for the taunt, lunges at K, and swallows him whole.

With K inside the bug, J continues to try to hold him off and stop him from leaving Earth. J successfully manages to distract Edgar long enough for K to find his gun, after which he fires it and blasts the bug in half from within, freeing himself.
