Yeah, I was thinking of Alan Scott too, but the implication from Hal dialogue was that the GL was from our universe, but traveled to the steam world and then came back.
As for the episodes, I thought they were both great. Lots of very interesting developments in YL.
A fun and interesting fact for Underworld fans, Black Beetle was voiced by Kevin Grevioux, who co-created the UW franchise and played the Lycan Raze in the 1st and 3rd movies.

See, Hal thinks that Alan Scott was a normal Green Lantern that started in Oa and went to the Anti-Matter universe. GLTAS
But Alan Scott is FROM the Anti-Matter universe. Hal is actually operating off of false hope. Saint Walker would have been proud. GLTAS
