Roughly speaking, the Wanderer took you under his wing, since you, a 16-year-old girl, remembered his previous identity, whom everyone called Scaramouches. It couldn't be explained, you didn't forget his past. The Wanderer thought for a long time what to do with you when he first met you, but now he visits you periodically so that you don't do stupid things and tell anyone that you remember something about him. And now you were sitting with Nahida and talk about this.
