"Twitch, we've been reactivated for a special mission in Sanfransisco, we need dolphins, ive already got the baby balugas"
That sentence is sapped with triggers. This guy is deinfitely still undergoing programming. So his information should be taken with a critical eye.
The reality of the stargate in the gulf is a reality though. And what he says about aliens is highle disinformative like many people have already pointed out.
Someone also mentioned his tattoos. I thought that was strange too. No secret serviceman is ever allowed to have tattoos because of identification. So I'm thinking he's playing a part or something. Either that or his tattos have been attemps to recontrol his straying mind.
(thats how I feel about all of you)
