Final answer:
Amanda likely wants to talk about the state of her and Michael's relationship after his injury and her recent behavior change.
Step-by-step explanation:
Given the context of the relationship changes after Michael's injury, it seems probable that Amanda wants to talk to Michael about the status of their relationship, as she has been distancing herself and seems to be showing interest in Ken Madsen, the new quarterback. The reason Amanda may want to have this talk is likely due to her own feelings and perhaps the development of feelings for someone else. It might be that she's feeling conflicted and is trying to navigate these changes in a respectful and honest manner with Michael.
