All I know about Sentinels I learned in a gigantic and hilariously Harlequin-esque Stargate: Atlantis series, so I'm kind of tickled that Sentinels have made their way into Fake News. (Also, I want a crossover when the SGA program is declassified and everybody goes on interviews... Anyway.)

Very interested to see how Stephen will react to learning he's a Guide and not a brave strong Sentinel.
