We're heading to New Vegas in Season 2, and this is the only character I really would like to see resurface, mostly because Yes Man saved me from never finishing New Vegas. I was starting to get bored with the plot and Yes Man brought me back in.
Dave Foley killed as it Yes Man, and I would love to see him back in the role. I was a big fan of Foley from Kids in the Hall/News Radio days, and I was overjoyed when I ran into Yes Man and recognized his voice. Dave Foley has exactly the kind of absurd cheery demeanor a character like Yes Man needs.
Further, I'm going to assume the Courier/Yes Man taking over the Strip ending of New Vegas probably isn't canon, it means there's ample opportunity potentially for Yes Man to continue being the best Yes Man that he is.
Hell, I'd love to see any of the Kids in the Hall in Season 2, honestly. Kevin McDonald keeps looking weirder every fucking year, he would fit in with wastelanders. Hell, the new Kids in the Hall season was an Amazon Prime show, and both Kevin and Dave went full frontal nudity with their weird old bodies. They're the right kind of fit for the wasteland.
I would also think Foley's "Doomsday DJ" sketch is a great example of why they need him in Season 2 of Fallout.
I came back to this thread because I watched through the credit sequence from the final episode of the series, which starts on a billboard inside the New Vegas strip, backing out to the "Welcome to fabulous New Vegas!" sign.
Trashed Securitrons and evidence of what looks like a fucking warzone, right on the Strip, including a downed NCR Vertibird.
The main gate to the Strip busted down and wide open.
It seems to me like the canon endings went bad for everybody. New Vegas ends where it ends, and we don't know the far flung future of everyone involved. It could easily be that a war between Mr. House and the NCR fully broke out, leading the NCR to heavy losses and abandoning New Vegas. While everyone's whinging about the NCR I'm way more interested in what's happening with Cesar's legion.
Once again, like in real life, this doesn't mean the NCR does not exist elsewhere, but none of it is unreasonable nor does it "wipe away" the events of New Vegas. It just recontextualizes them in a new story.
Further, as this is a TV Show, this is many people's first brush with anything Fallout related, and it makes sense to try to sort of reset the world to the post-apocalyptic state of Fallout 1, to give the people coming into the series now a similar feel of the originals. They could have just as easily started the whole damn thing over, ignoring every canon storyline, just like the Halo show. All things considered, I really don't get the hateboner for this fucking show some folks have.
