Giblet definitely loves Poppy very much. On the tape, however, Poppy doesn’t act like her father has died, but rather as if she just can’t reach him right now. The Prototype wants her to suffer because it hated Elliot. What could be more painful than being an Outimal? Also, the name Giblet fits both Elliot and Ludwig. From the pangs of conscience he experienced in the past, he constantly tells us that he was never truly a hero.
But these aren’t the important parts. What matters is that after throwing us into the Prototype’s Poppy jelly, it gives us electricity so we can be revived. How could it know that? Elliot Ludwig realized that Poppy jelly alone didn’t work, and he personally tried giving electricity after the jelly to bring rats back to life. How many people could possibly know this?
