That being said, it works for the most part.
Oliver tells her Earth-2 is gone, but Laurel refuses to believe it.
Arrowhasnt always known what to do with Laurel, giving Katie Cassidy weird and clunky plotlines here and there.

Thankfully, this isnt one of those times.
What elevates this entire arc is how the show ties it back to her redemption story.
They manage to track Dr. Wong down, but China White (surprise guest star Kelly Hu!)
and the triad show up and kidnap him.
In the fray, Oliver ignores innocent civilians as he chases after her, but she gets away.
Seeing no other option, Oliver decides to offer China White a trade: the virus for the doctor.
Havent we been down this road before?
The answer is yes.
This time around, Oliver feels guilty for Earth-2s destruction because he disobeyed the Monitors orders.
Oliver ignores Tatsus warning and goes through with the plan.
Naturally, things go sideways.
Little does he know that the Monitor has someone else working for him: Lyla Michaels.
Its clear that theyve been working together for a while.
In fact, the episode hints that this partnership may go all the way back to Lylas army days.
Laurel asked if it helped, and Lyla says, not exactly.
Is that when she met the Monitor for the first time?
The past also weighed heavily on the future story line.
Its clear J.J.s difficult childhood is driving his evil actions in the present day.
Only time will tell if Connor will be able to sway his brother off of this dark path.
