The idea of heroes has been a central part of this series from the start with Joey wanting to be just that and getting an opportunity to do so. What's been interesting about it is that not only has he been a controlling figure over the main hero of the series, Heroman, but he's also had a number of heroic moments himself. Rather than keep completely to the sidelines and just ordering Heroman around, he's managed to get out into the action pretty often and put himself at risk as well. Whether he realizes it or not, he's done a good job of defining himself as a hero, even as he's being asked just what is a hero. And for Joey, a lot of that comes naturally because of his father.
Through a flashback, tinted through Joey's eyes, we learn of a mining accident years ago where his father ended up being the rallying voice in keeping people alive but he was also the one who sacrificed himself so the others could live. There are many in town who remember him very well because of this and that's something that really warms Joey's heart because of his love for his father. Which contrasts the existing family situation that Lina has as she's still very concerned about Will, who has actually come to visit her in the middle of the night to check on things at the house. He won't return fully, and that haunts her. Even more so because her father has now said to no longer concern herself about him because Will is dead. Will's disappearance and presumed death during the Skrugg invasion has driven a strong wedge in the family that isn't going to be easily repaired.
