Arrow S03E08 Still - H 2014

[Warning: Spoilers ahead from the Arrow/The Flash crossover episode, "The Brave and the Bold."]

The CW's Flash-Arrow crossover event finished up with Wednesday's Arrow hour. While the biggest Arrow moment occurred during The Flash hour (as Oliver ran into his ex/baby), a few important things went down in "The Brave and the Bold."

Here's what the Arrow cast and producers had to say about some of the crossover's biggest moments.

Diggle is engaged!

After Lyla (Audrey Marie Anderson) survived the attack against her, Diggle (David Ramsey) decided to make things official with his ex-wife/baby mama, so he popped the question to her — again.

And while happier moments are fairly hard to come by on Arrow, Ramsey confirmed viewers will get to actually see a wedding onscreen, though he was hesitant about whether the newlywed (and new father) bliss will be long-lasting. "I don't know," he admitted. "That was softer … the stakes are high. Diggle's working, and he has a wife and daughter to protect."

Oliver is going to a dark place.

Oliver (Stephen Amell) may have loosened up a little bit at the end of the crossover to take on Barry (Grant Gustin) for a playful one-on-one fight, but the lightness will vanish almost immediately in the next Arrow episode. "The smile you saw on Oliver's face? It lasts for about four seconds in the next episode, and then it's gone," Amell teased.

The impact from the crossover will continue to play out.

Not only is the STAR Labs team now actively helping Team Arrow with the search for Canary's killer, but Arrow and The Flash executive producer Andrew Kreisberg previewed that "there's a couple of big STAR Labs inventions that will be coming Team Arrow's way."
