Chapter 8: Not a Chapter

So I said before I didn't want to keep MC in the MCU for very long. She will still return here occasionally, but she will lay her roots in the 616 Comics universe. But before she does, I want MC to have a few more adventures in the MCU. To give her an idea about the heroes and villains on earth, space and in other dimensions. I already have one such adventure in mind but I'd appreciate it if you can recommend any other possible way for her to interact with other heroes from different walks of life.
