First thanks for letting me know the panel was available on YouTube.
I enjoyed watching it.
They did also discuss their turns on Smallville and Supergirl.
I frankly wish the Supergirl producers would have NOT introduced a young Clark Kent and Superman. I think it would have been so much more fun to have Teri and Dean as the Lois and Clark of the Supergirl universe.
I noticed as I was listening to the discussion that a number of their ideas have been explored in L&C FanFics
