Thats awesome. The plant will push out new growth from the rooted end.
Just DO NOT overwater it. It doesn't need anything until it's growing.
The loose end is easily rooted as well. Do not do a humidity tent.
Those two big leaves, cut 1/2 to 3/4 of them off, they'll be fine.
You don't need to remove the stem below the node, but it will rot off eventually, so best to cut off whatever isn't needed to anchor the plant.
I suggest not rooting in water, water grown roots are very fragile and the plant often goes into shock when planted. Best to root in a a very course soil, I always used crushed gravel, but any sandy type soil works well.
On our one sandy lot, i used to have Salvia leaves that fell off root in the sandy! sadly they never formed a plant and eventually died.
but I ramble.....
