It's not 'Twisted Sister' but may have came from a leaf cutting of same. It looks to be Sans. trifasciata hahnii. But check to see if it has a keel down the center outside. Or some times hahnii Seabert does't show it's slight variegation until later. But sure looks like regular hahnii.

BTW dwarf zeylanica is another name for hahnii. Not used much anymore.

Many thanks
