Lethe's Latent Element

It wasn't a surprise when Lethe's latent element was idenfified as water, considering at some point in her youth, she'd develop hemokinesis. It's a rather unorthodox way her element would theoretically manifest, but is a useful tool nevertheless. She's currently only able to manipulate blood in liquid form -- she's currently studying a way to perhaps transform it into physical objects, impromptu weapons perhaps?
