It seems that the first version of Intersect (the one young Chuck accidentally downloaded) was running on a Commodore Amiga computer. Apparently it was quite buggy, as there was the infamous "Guru Meditation" clearly visible in the screen.
When Chuck poses as Yuri Shishenko and he says good-bye to Shaw, it sounds like "Do stavan'ya" while the correct "good-bye" in Russian sounds like "Do svidaniya".

Awesome: What are we going to do? We don't have a plan.
Morgan: No plan? Never stopped me before.
Chuck: All right, that's it: we break into the convention; we expose Shaw; and we capture the elders.
Casey: Conference will be surrounded by an army of security agents and filled with spies. Suicide mission.
Chuck: The only ones who could pull it off would have to be the best spies in the world.
Morgan: Chuck, you're embarrassing me.
Sarah: You ready?
Chuck: I was born rea... well, no, actually, no, I wasn't born ready, but I am ready now.
Shaw: So what's happening?
Chuck: You're under arrest.
Shaw: No, what are you doing here? What's your plan?
Chuck: I'm sorry. Are you asking me to make the classic villain mistake of explaining my dastardly plot to you? You know what? I'd love to.
Shaw: You have to do it. You have to kill me.
Chuck: No, thanks. I've already done that once before.
Shaw: That's what makes you weak.
Sarah: (strikes Shaw in the head with a metal bar) No. That's what makes you great.
Ellie: I can't believe that he's gone. Our crazy dad.
Chuck: He wasn't crazy. Our dad was a hero. He was a great man who did amazing things. He was not perfect, not as a dad, no, but he was great. That's the secret I most wanted you to know.
Ellie: Is my husband safe with you?
Sarah: Uhm...yeah. Why?
Ellie: Because Chuck and I need to talk.
Casey: Hmm. Two Bartowskis. Double the fun.

The flashback in between of Chuck's final fight against Shaw, young Chuck is seen wearing a Superman t-shirt. Brandon Routh who plays Daniel Shaw, acted as Superman in the 2006 film, Superman Returns.
When Casey and Morgan apprehend the five elders of the Ring, Morgan states that "you people are the disease and I am the cure".
This same line was spoken by Marion Cobretti (Sylvester Stallone) in the 1986 movie Cobra. "Cobra" was also the code name Morgan selected for himself in an earlier episode.
