So lets talk about Lulus Spoiler.
Since I ve seen that scene and know what you were talking about.
I did not see that coming.
Thought Reginald would have been some kind of time/dimension traveller.
And thats why he has known about the 2019 Apocalypse, but that he is an alien, was unexpected.
Love Fives fight with his older self, and all those farts.
Edit: watched the last episode.
What the heck did they fucked up in the past? Sparrow academy? Harlem?
Seriously they are pretty bad in let the timeline like it should be. XD
