I looked at your photo and I see at least 4 plants in there. It could be a trailer, but I think the leaves on a trailer tend to be smaller. I would unpot and divide all of the little plants in that pot with a sharp knife. I would also bag the plants that you repot. It should take about a month or so for both the plant that only had a crown and these plants that you divide and bag. I generally see a plant bounce back after bagging soon afterwards.
Good luck to you.
