Questions about two achievements

[Yan17]

First, thank you so much for creating the game, I had a wonderful time with it!

I am now aiming for a second playthrough and I want to change a few choices while collecting the remaining two achievements.

The ones I am missing are Lifelong Friends and Wind May Blow.

For the first one I know that I have to remain friends with Kelsi. In another thread about the same topic it was said that you should not fight with her when she leaves and tell a nice story about her at the campfire. I did everything mentioned, but she never came back. I only ever got a letter from her. I did blame her in the first chapter and won at the card game, maybe that is an issue?

About the second one, it's obvious that I need to get Isaac to return to Pyreside. Brianna came back (there was a certain achievement related to her), but her brother didn't. Are they mutually exclusive? Maybe it has something to do with who I have to give the stone to. Or is it about blaming him or her when they fight about the toolbox?

Any help would be greatly appreciated.

Isaac came back with his sister, when I let them keep the money found in the room of the old blacksmith. It seems they hired someone for the shop in the other city, so he was free to return later. I got both achievements in this run, when I touched their graves in the last chapter.

For Kelsi as long as you talk with her in every chapter and reaffirm your friendship every chance you get, she should return. I beat her at cards and blamed her without any issues with her returning. Interesting about how you can get both twins' endings unlocked in one playthrough. I didn't know that was possible, I thought it was one or the other for a single playthrough. Would've saved me a final playthrough to get Issac's and 100% completion.

Maybe you need to confide in Kelsi at the end of chapter 3? I'm not sure, she returned in both of my runs, even when I confessed to her. I'd do what the above says, just make certain keep talking to her in every chapter. You don't always have to be super nice to her, you can beat her at cards and blame her for the theft, but don't fight with her. I don't think you even need to tell a nice story at the campfire, you can tell an embarrassing story and she seems to take it in stride, just asking for a glass of wine while she thinks of an embarrassing story to tell about Lyric. Though at this point I already had the achievement so I can't confirm 100% that you still get it if you do this, just that it doesn't seem to ruin your friendship or anything.
