Lyla and Monitor in “Unfinished Business”

Lyla

You should've told me what was going to happen on Earth-2. John was there. He could've been killed.

Monitor

The destruction of that Earth was a necessary sacrifice.

Lyla

Monitor

Countless more like them will perish if we do not ensure Oliver Queen is prepared for what's coming. Were you successful?

Lyla

Yes. I have Dr. Wong.

Monitor

Then let us proceed.
