I love all the callbacks in this chapter.
In the very first chapter, right before he died, Denji told Pochita that he wanted to eat good food, flirt with a girl, play videogames and fall asleep in her arms. That was his dream and, thanks to Power, he did all those things. That's why he lost the will to live when Makima killed Power, because he truly did believe he had done everything he wanted to do and without his friends and with Makima's promise to destroy anything good in his life, Denji believed he had nothing to live for. So in giving him a contract to find her, Power has given Denji something to live for and snapped him out of that hopelessness. It's pretty damn fantastic and further messes up Makima's plans because she clearly thought she had gotten Denji out of the way.
I really like that the tiny dumpster Power and Denji talked in and made their contract together is the same one that Pochita and Denji talked in and made their contract together, too.
