By itself, maybe it was, but it's is probably to set up him as a villain.
The whole plot seems to revolve around the mistery and his family, so the dev must've wanted a big introduction.
Really liking the game so far, and despite being AI, which can be know by its sloppyness, it's obvious how much care it went on the game.
The images are really consistent, even when changing little things, and the animations transitios are top notch.
Already one of the most well done Ren'Py games I've seen.
Looking forward for more.
