Black Adam making the save for Lois and Jimmy (however inconsequential that fact might be to him) from Ultraman was all sorts of win. Liked the unpredictability of it.
The hooded man has to be Alexander Jr. Grid confirms the guy has power of some kind. Lex Sr. never did, as far as my recollection. However Superwoman indeed being Earth 3's Lois, like the antimatter version, kinda throws a wrench into this. Unless it turns out she took over the identity of the true Lois Lane or something like that, or they just give him a different mother in this continuity.
