Three Questions Following ‘Arrow’ 8×03 “Leap of Faith”

Tuesday’s episode of Arrow saw the return of a fan favorite and one shocking ending that leaves fans with more questions than answers.
Speaking of questions, here’s three that I have after 8×03 “Leap of Faith”.
Does the crisis change the future?
WHAT WAS THAT ENDING?! For those who haven’t seen the episode, here’s a quick rundown of what happened in the last five minutes:
Future Team Arrow went to the Deathstroke Gang’s hideout to try and take them out for good. JJ kills Zoe and an angry Connor tries to kill his brother as revenge. But before that happens, a bright white light engulfs everyone and the next thing we know, Oliver is back in the bunker in 2019.
But that’s not all as things get even crazier. Dinah and Rene are stunned to see Oliver, but even more shocking is seeing all of them come face to face with future Mia, future William, and future Connor Hawke.
“Dad?” asks Mia as the episode cuts to black.
Okay, so does the upcoming Crisis change the future? With news of a spin-off planned surrounding Mia and the Canaries, I had wondered just how they would introduce the idea of the Canaries and how they would have Mia take the mantel from her father. If Mia sticks around in 2019 (and that seems likely given the promo for next week), it looks like that’s how she’s introduced to the Canaries.
Another question I have is how heartbroken will Diggle and Lyla be knowing that their son turns to the dark side in the future? And if Crisis changes the future, can Diggle do something in the present make sure his son doesn’t go down that path in the future?
Will Thea return for the spin-off?
Tuesday’s episode saw Willa Holland return as Thea Queen and it won’t be the last time we’ll see her. She is going to recur for a “multi-episode” arc and I couldn’t be more pumped about this since Thea is my favorite character on the show aside from Oliver.
During Tuesday’s episode, Thea invites Talia to help her turn the League of Assassins into a League of Heroes. She accepts which leads me to wonder if this will have any part in the upcoming spin-off. You can’t just throw out a new League of Heroes and be done with it after six episodes. I feel that this is setting Thea up for a guest-starring role in the spin-off alongside the female-led cast. The more I think about it, the more it makes sense.
How will Diggle react to Lyla working with The Monitor?
It was nice to see Diggle and Lyla have a husband-wife storyline; it really brought me back to the first few seasons of the show. This time around, Lyla was really enjoying the time she had working with her husband. But is it because she’ll be leaving soon?
We know that she not only knows but is working with The Monitor. The big question is how will Diggle react to his wife working with a cosmic-being and learning that she’s basically been keeping it from him all this time? Something tells me he and the rest of Team Arrow won’t be too happy with her.
