He should have shot you instead, because there aren't many other options for Jabba among us.
Actually, I could have pulled off such a trick, but why? If you're peaceful, it would be 3-2-1. At night, the Cop dies, and it becomes 3-1-1. Then, a triple shot, and I win. Why would I waste a decent amount of credits on you, just to set you up for a shot from Tarkin, who probably wouldn't even be there anyway (we have to assume that Leia was constantly interfering with him, meaning he still had to build his star). So, such a betrayal makes no sense.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
