How do you do that, btw? Use telekinesis on an arrow made of energy, I mean. Generally, telekinesis in most magical systems only works on physical matter, and shields are required to avert energy attacks. Going on what you've said thus far (and the fact that you haven't opted to use TK on the fire), Steve's magic works the same way.
While also defending against several other attacks at the same time? And splitting your focus to redirect an arrow composed of darkness energy? That shield isn't going to last...
