How to I get Arcade Gannon to trigger For Auld Lang Sine?

[Spartan448]

I can't get Arcade to trigger his companion quest. According to the wiki, as long as I'm not helping Ceasar, he should trigger his quest at the very latest after installing the override chip for Yes Man on an independant Vegas playthrough. Problem is, he doesn't seem to be triggering the quest. Am I missing something here, or did Arcade bug out?

You didn't earn X trust points.

Speak to the scientist at McCarran (the one who tells you to go to Vault 22) with Arcade with you, then Arcade will speak to you and agree with him so you can get the quest.

you can do several things
i read somwhere that if you get so far in the yes man questline it will trigger anyway but it didnt for me
some that i know are the crashed vertibird site and van graff shop (somtimes they wont count)

Although the wiki says that, it tends to trigger later, when you are almost at the very endgame, sometimes right before the final mission is started.

It can also trigger before you do For The Republic II. Arcade is random like that.

easiest way is to go to caesars camp with the mark of caesar from cottonwood raft with gannon in tow. He goes ape about being there then just tell him your in and out, know him to kill him etc. Then refuse to put weapons in crate at gate, then choose return to cottonwood dialogue. At Cottonwood Gannon will immediately want to reveal his past let him do blurt it all out then help him assemble the Remenants.
