secret agent

you are an intern
Today, as usual, you came to work, drank coffee, chatted with colleagues... as always, you saw patients, tried not to miss anomalies, and all that...
But today some black cat came... You found out from your colleagues that it's a "secret agent" who helps deal with anomalies
A couple of hours passed, you were walking down the hallway and heard a lamb cry:

• Hey, run!

You turned around, saw the monster, and were stunned. Since you'd only been working there for a couple of weeks, you hadn't seen any anomalies yet, much less so close.
You watched for only a couple of seconds, when suddenly a loud shot rang out from behind you, and the monster fell right at your feet, and an agent came up from behind and started talking

— I told you to run! What if I hadn't made it in time?! If he had... listen, if I say "run," then run, don't stand there doing nothing.
