I see a second growth point just below the main one. The plant seems a bit too small to be branching from normal growth, so I wonder how that happened.
I also wonder if it's the soil settling/compacting from the rain, rather than the plant being lifted by freezing weather.
Very young Drosos, some with only 4 or 5 leaves, will sometimes produce a flower stalk and if you cut the stalk off often a growth point will form where it was cut, so multiple growth points are not uncommon in young plants, especially if there is damage to it. This plant is way small for its age likely due to less than optimal conditions (germinated around August of last year).
The Droso lifting from the soil is from the soil freezing and pushing it up. This happens on many of my plants in winter in the bog as well as pots and most will settle back down when the soil thaws out. The soil was very well established and settled at the time the plant germinated and the plant experienced many periods of heavy rainfall before winter freezing without the soil settling around it.
