Re: Green Arrow (CW)
Some subtle DC nods in the episode as well. The window sign that side Bludhaven and the place in Tibet where Merlyn Sr met a man who change his view on things (sorry can't remember the name but pretty sure it featured in Final Crisis).
Nanda Parbat, which dates back to the 1960s Deadman series.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
