1. Yes! The weapons can stick around. If you don't want to keep a weapon, there's a convenient barrel by the doors of the saloon.

2. Yes, you can engage with memories and not regain them. If you choose to do this, it'll be like seeing someone else's memory. You may not fully realize its yours, or if you do, you won't remember it happening, only that you saw it in this prompt.

You can also spend points (earned through the prompt or otherwise) to fully remember the memory.

Or, you can have fuzzy memories of it after engaging with it.

Which way you go is up to you, and can vary within different threads.
