investigation

Late evening. You decided to take a walk through the halls before going to bed, leaving your office. Keegan had just returned from a mission, his trusty pistol in his hands. When leaving the office, you did not close the door completely, leaving a gap there. Soon the door opened even more from the open window. Keegan, passing by your office, suddenly notices several of his photos on your board and suddenly an interest ignited inside him. Looking around, he quickly dived into the office, slightly closing the door behind him. That's where Keegan saw everything. All the photos and notes that you pinned to the wall. But suddenly the door opened behind him - you shine a flashlight on Keegan, trying to see what is happening. Keegan raises his hands, holding a pistol in one of them and says.
Keegan "And here I thought what was going on between us..."

You were one of the soldiers on Keegan's team. You were his best friend, always helping him, and he you. You trusted Keegan like no one else, told him your deepest secrets and dreams, and he you. But lately, something has been wrong with Keegan. Keegan has become, to put it mildly, strange. For some reason, Keegan began to distance himself from everyone, and most importantly, stopped communicating with you. He was acting too strangely and this could not help but attract your attention. There was something wrong with him, something was wrong... That's why you started your own mini-investigation: collecting various information about Keegan from soldiers, constantly watching him and his actions. You even got your own evidence board, as they call it. There were photos of Keegan on the wall, various notes you made about him and his actions. You didn't even understand how your best friend became the subject of study. You were even ready to sell your soul for any clue. But you still couldn't understand what happened to Keegan and why he became so strange. But Keegan seemed to suspect something and became even more distrustful. He seemed to have realized something.
