Final Fantasy VII Remake Resolutions

SPOILER WARNING!!!!!!

As you progress through the game, there will be a cutscene between Cloud and either Tifa, Aerith, or Barret in Aerith's flower garden. Of course there are mechanics behind this. Choices made will go towards who you speak to. The exact mechanics are, as of typing this, still unclear completely. So what I am going to do is provide what I did in order to get each of the scenes.
It should be noted that you can only get one scene per go through. So you will have to begin again, or open the "Chapter Select" by ending the game, in order to see each of them.

~Tifa's Resolution~

*In Chapter 3, complete all of the side missions.
*When offered a drink, accept the drink.
*When you fall into the sewers, wake Tifa up first.

~Aerith's Resolution~

*In Chapter 8, complete all of the side missions.
*When offered a flower in Chapter 2, choose "How much?".
*When you fall into the sewers, wake Aerith up first.

~Side Note~
It should be noted that I did all of both Tifa and Aerith's side quests, and was able to begin at the sewers before waking them up to get both videos. The only change I made was WHO I woke up first. So if you are looking to do all the missions, you can save right before waking them up, and see each by making the choice of who you want to wake up. But with the both having their missions done....there is absolutely no way to see Barret's Resolution.

~Barret's Resolution~

*In Chapter 2, do not accept Aerith's flower.
*When offered a drink by Tifa, decline it.
*Do not do any of Tifa's quests in Chapter 3.
*Choose the "No promises", when asked by Jessie to come back the next evening.
*Do not do any of Aerith's quests in Chapter 8.

In my own opinion, I do not think anything matters other than the side quests you do/don't do for Aerith and Tifa. If you do none of eithers quests, you get Barret. If you do all of Tifa's or all of Aeriths, and you choose that character to wake up first...you get them.
Each are indeed very powerful. In all honesty I had not thought about the fact that Shinra destroyed Tifa and Clouds life not once...but twice, UNTIL I watched the cutscene. It was very moving and powerful. And you definitely see Clouds hard edge break.
Barret and Cloud I think truly bond in his scene. Nothing emotional, or over the top....but if you are close friends with another dude....you recognize the kind of opening up between them. It is, as a guy, hard to explain. But it is powerful for those who have gone through the same with their bros.
Aerith hit different. The first time I saw it, it was emotional. She knows what is going to happen, and what she must do. And she is trying to save Cloud, someone whom she truly cherrishes, from suffering.....but upon further viewings, I think there is more in it than just that. But I am not going to speculate on it at this time. Each are definitely powerful. And the further develop not only the characters whom they are for, but the bonds between them and Cloud. Certainly worth seeing each one.
