Some fantastic episodes are happening in season 3, especially the crossover one with the Flash.
I'm loving how Barry's presence in Arrow brings a little humour and the bonding between him and Oliver is brilliant. I jumped for joy when Oliver was introducing Barry to Quentin, who instantly called Barry - Bart Allen, that's gotta be a nod to SMALLVILLE where the Flash, more known as Impulse was called Bart Allen.
I'm not sure what is happening in the Hong Kong flashbacks, I must have missed something, because it's not making sense.
Who killed Sara is frustrating me, first we're on course that it's Roy, but that's now been proved wrong.
