John approaches Jack, backing him into a corner and says, "There's nothing that you can help me with. You depend on you powers for everything. Instead of walking, you shoot webs everywhere, leaving a mess for others to clean up. Instead of climbing the wall like everyone else, or realizing that there was no point in doing it, like your brother, you decide to show off and climb it without the hand holds. Maybe you haven't noticed, but when I have my powers, they're stronger than yours in every way. I help people with my powers, you use yours as a crutch and a way to show off. I've had enough of that."
