Technically speaking...

Panel 4 - Robot Julius explains to Connie she's not immune to death as she stated in the previous panel, she could still be killed by acts of god and is safe only from growing old, which isn't bad if one takes care of oneself and plays it safe. Connie seems indifferent to her Robot's comments, of course what he's saying isn't news to her, Julius is simply wasting his breath. More to come...

The Infinity Serum

Panel 3 - Connie, with one hand holding the Infinity Serum and the other a glass of delicious French champagne, says a few words to celebrate the completion of her DIFFICULT and IMPORTANT work: a secret liquid formula to conquer DEATH! A scientific breakthrough so PROFOUND it must come with all sorts of DANGEROUS and EXCITING consequences. And what's her robot assistant saying? Ha ha, Correct! It's the proverbial Hebrew "L'chiam!" or "To life!"

Better come back soon and see what those consequences are...
