But... Were talking about Supergirl. Or at least I thought lol. I meant S4 of SupergirlOkay, got me there.
But S4 killed off OG Laurel when she was getting some redemption had that infamous walk off scene and forever poisoned Olicity.
Now I understand what you mean as I re-read your post. idk, Flash Season 2 had some really high moments that helps out the dumb Zooms stuff at the end. But, yeah that year Supergirl probably had the best season that year of the bunch
