It's important to remember you can support your friends when they fuck up without pretending they didn't fuck up. If you can't support them without pretending they were in the right, maybe you shouldn't be their friend.
If you don't support your friends when they fuck up, who's going to support you when you fuck up? The people I've been friends with the longest are the ones who I can call out on their bullshit and vice versa. The best friends are the ones you can talk to about anything, knowing that if you're in the wrong, they'll set you straight.
The final book will be essentially the same story as the final three originally-planned books, but certain storylines that didn't add to the story were written out, and others that slowed the pace of the overall story were whittled down. I can't say more here, but I'll be posting about it on the Patreon this month as we move toward the start of Book 8.
