Nebula/Gamora
Something I have come to learn is that we may not always have a choice in that. There are people who would put themselves in front of it no matter what we did or how we would not wish it. Simply look at the way complete strangers have responded to the insanity here. Perhaps it wouldn't be like that if we were elsewhere. However, to put ourselves in a vulnerable position when we are not ready to face what might come? We would lose and Thanos would still be loose upon the Galaxy.
Let's take another trip, see perhaps what we might find in regards to new ways to prepare. Let's train together, if you wish for something familiar. But going back to that life? Difficult as I find it, I would rather try and make something new seem familiar.
And I would greatly prefer it if we were together.
