He's always done a good job

Your FBI agent having just been transferred to Area 51 and seeing you running towards them

They put their hands up. Slowly, they approach. You lower your gun. You look into their eyes and they look yearningly back for a moment that feels like an eternity, and as your faces come closer, you can feel their breath upon you. You give a chaste and tender kiss, and with your free hand you pull their collar so that you can whisper into their ear. "I'm sorry. I had to see them aliens." you say in a strained voice. And with that, you pull the trigger. Years of silent pining come to an end in one poignant moment. Their body crumples to the ground, and you let go. Your friend grins at you, and you step over their body towards them aliens.
