3 questions:

1. If you let Benny go in Ceasar's tent, will he make another appearence for an epic showdown? Or does he wander off into the wild blue yonder?

2. If you chose not to destroy the securitrons, can u lie to Ceasar and say that they are all taken care of?

3. Does this dress make me look fat?

1. I think he might be at the tops

2. Yes

3.no the cake does though.

He currently disappears from the game after you release him at the Fort. However :

"An event would have Benny meeting the Courier again after being freed from the Fort. In the event Benny would have equipped a Stealth Boy in order to sneak up on the Courier, and initiate dialogue in which he would mock him/her for showing him mercy and after that go into attack mode, which would most likely cause him to be killed by the Courier. This event was cut from the final game."

If you're on PC, I believe I've seen a mod or two that restores this event.

I'm on Xbox... I just want him to die due to no fault of my own... like after I become King of Vegas he comes to grab control from me... I want him dead, and even more so... I want Maria. but I have moral ambiguity of crusifying him, or butchering him with a machete in the arena.
