The trip changed him in many ways, some better some worse.

Suppose he cared a little bit more about things, staring to appreciate small things much more, especially after most of his friends died on it. Luckily you survived.

You were in bad shape for a few months, eventually recovering and showing up to school once more. Thrust into the daily hustle of the world.

You noticed Jotaro's differences after only a week being back, he seemed to not exactly be the most fond of people talking to you, it got to the point you down right avoided him. You knew it was rude, you only just got back only to avoid him. But it felt like he was going overboard.

He didn't like that.

Not one bit.

Over time he had become paranoid of losing the people he had left, you were the only close one left. Polnareff went back to France and Joseph was with his wife. You were all he had. He couldn't just let you get away. Not like how he let the others.

He waited, watching closely. He had been developing his stand, and it could be used just for this. To stop time, take you away. So then you couldn't leave.

He got you.

Stopping time with his stand, he reached out and grabbed you, taking you all the way back to his house. Tying you up and putting you in his closet. You woke up, eyes adjusting to the dark as you gazed up, eyes locking with his stand, Star Platinum. It just stared at you with a blank face, watching. Like some guard dog.
