If we ever need to know something, it looks like David is the best person to ask about spoilers. LMAO. I LOVE HIM FOR THAT!
Honestly David is the best. He always comes to play. So based on these spoilers here’s what I’m thinking: The secret could be that Diggle is more injured than he lets on from the explosion. Eventually Oliver finds out. Susan William outs him as GA or Oliver decides he has to out himself as GA. Diggle decides to step in as GA but Oliver doesn’t want him to because he could hurt himself more or even permanently in some way. Thus the big clash. However, David said this is the storyline for the first six episodes. So I’m thinking the Bromance is repaired by the time we get to the crossover, which would coincide with the timing of the Olicity wedding that Stephen hinted to me! I AM SO LIT FOR S6!!! I love that this storyline puts a laser focus on Diggle and his relationship with Oliver. One of my big disappointments with S5 is that they benched Diggle. Echo also talked about Smoak Tech so I think that will be getting kicked off too. Really strong storylines for OTA. Can’t wait.
