I don't really care about what will happend in A4. The think I really care about and I need Marvel to give us is: The 5 years after the snap. Even if it means Ned and MJ graduating without Peter. Even if it means Shury ruling Wakanda without her big brother by her side, Even if it means Tony blaming himself for what has happened. And not stoping after being assured like million times that its not his fault. And even if it means Thor being extremely sad about Loki's death. Or Rocket being without his "family" for that long time.
Because after that I need Marvel to give us time right after A4. To give us Peter hugging his friends again, swaering that he will never leave them. To give us Peter Quill meeting Gamora and being sorry about what he did. To give us Steve speaking with Bucky again. To give us Thor almost crying that his beloved brother is back, telling him, he will never let him die again. To give us Mr. Stark having baby with Pepper and finally stop having his nightmares and anxiety attack. And finally I need Marvel to give us Dr. Strange watching this from distance, smiling happily about the fact that he was right all the time.
Because my lovely characters showing out the emotions is more worth it than whole how-to-actually-kill-thanos-concept (A4) and all the heroic scenes in it.
