1.) Ferris Air again, which is owned by Carrol Ferris.
2.) A test pilot goes missing, probably Hal Jordarn. Now whether he'll be allowed to be used on the small by DC/Warner Bros is another story.
3.) The Reverse Flash costume comes out of his ring, this is how The Flash/Barry Allen in the comics used to store his costume in his ring, Wally West would later use the speed force to form his costume.
All i will say about the finale is never saw that coming, none of the internet rumours and theories actually played out. The Finale was heart breaking and breathe taking at the same time. I know some stuff about season 2 but will save that for when the finale airs in the UK. As always with every finale a shock ending
