When you send a Juggernaut to the Auction and do not tell him that it is a stealth mission
In this timeline of Entry Point, Halcyon's only operative for this mission is this juggernaut guy and they
A. Don't brief him that it is a stealth mission, and
B. Let him have a Thumper.
Why did I made this you may be wondering... I do not know, I just felt like it + I had this dumb skit idea for like a while now.
