I don’t think hes “that” jack. I think hes just some guy named Jack. He probably has a backstory (what teenager is running around on their own, since he met henry when he first arrived in the EF 2.0 and he was just a teen/18 year old) but I don’t think hes from the beanstalk.
He and Henry mentioned giants, so seems pretty clear he is either Jack and the Beanstalk’s Jack, Jack the Giant Killer’s Jack or both.
Did he really? Oh god I need to do a rewatch, I totally missed it :/
