Frank + food
Living as Pete Castiglione, we see Frank eating sandwiches (peanut butter and jelly) day in and day out at work, proper actual food. When he slips back into being the Punisher, Frank eats ready made food or rations, on the go. He never considers looking into David’s fridge to see all the ingredients perfect for a sandwich. Because he’s a soldier again, eating rations, enough to sustain him. Food is not a luxury, it is a necessity. Then we see David giving Frank a choice of microwave dinners. He starts becoming more than a soldier, making personal choices of the food that he prefers. He eventually eats fresh pasta that David made, and then even makes David a dish of his own. David helps Frank slowly break out of the Punisher persona, becoming more than a soldier, but rather a person with likes, dislikes, with skills that aren’t just about killing people.
