If there's one thing this show proved with this episode - besides that it's an abstolute must-see and a joyride all through - is that Constantine needs to come back. It's clear this show came on air too early and I think that now, after Iron Fist, Defenders, and everything else, the world is ready for Constantine's return... I mean... Black Lightning gets a show... Why not Constantine.
Also... more Legends, more Rory, more Snart (which won't happen alas), more, more more.
