I only really knew Blue Beetle from Young Justice and tangentially after reading the Death of Superman comics years ago. Reading up on Ted Korrd really makes it more sense to be him than Ray Palmer, but I like what we got.
[Also fun that once he suits up, he flies by the open window on an upper floor on a building in a city which is CLEARLY very cold according to everyone else outside in this episode. Why the open windows? I'd expect that sleeping with Felicity WOULD be pretty hot, but still...]
Regarding Ra's, I suspect his hot tub is intended to be a reference to his Lazarus Pit, and we may even see it again as it's an expensive prop to be seen for all of ten seconds in this episode (unless the prop was a pre-existing rental). He mentions meeting someone in 1854, which obstensibly confirms his immortality (but true to the tone of this show, they don't dwell on it). However, I'm wondering if this whole inheritance thing means that Ra's as a person is effectively a TITLE that is passed on, and that the Ra's that was in 1854 is not the same person that is Ra's today, but the latest in a long line of people maintaining the legend of Ra's Al Ghul as an immortal force of nature. I wonder.
[And Ra's pronounces his own name as "raysh" here per various DCAU entries et. al., where everyone else sticks to the more Nolanesque "rahs" except for the DJ guy last week. Methinks some actors are researching outside the script's pronunciation guide]

I like how much Diggle-time we get here - so much so I was worried he might actually be killed. He's always been a voice of reason for all these younger vigilantes, and I think that should be expounded upon more. Also, he may be too cool for one, but he really needs a disguise.
I'm not the most familiar with how prisons work in the US, but if Iron Heights prison is shared between Arrow and The Flash, DOES that mean that both cities are in the same state? Papa Allen was in for murder while Moira was there awaiting trial for conspiracy to commit murder (or terrorism or something). Could Iron Height be a federal prison?
In the DC comics, Keystone is actually in Kansas and the home of the Wally West iteration of the Flash. I really doubt that would be maintained here, as Starling SEEMS to be an analog to Seattle while Central is somewhere in the midwest (or not, obviously it's purposely vague).
