Interval 12 - Epilogue - Aftermath is the final Interval of the game right after Point Man escaping from the Origin facility and confronting his mother Alma.
This is the ending cut-scene of F.E.A.R. First Encounter Assault Recon.
In it the Point Man is picked up in the chopper by Douglas Holiday and Jin Sun-Kwon. He regains consciousness in the chopper as a mushroom cloud rises over the city.
Holiday: "I don't know how you lived through that... we still don't know the extent of the damage".
Jin: "We haven't been able to get through to anyone since the explosion... what about Alma? what happened to her"? (the helicopter rocks and there's a banging sound) "What was that sound?"
Alma Wade is then seen pulling herself up into the chopper, ending the cutscene.
