The parasite in question is currently lodged in Willow's lower nasal cavity. Growing, but not quickly.

Then it has a spell directed at it.

That definitely does something.

Namely, the elemental decomposes the spell into raw magical energy and begins feeding on it, growing at an accelerated rate. This results in tiny little tendrils growing deep inside Willow's nose. Not where they're particularly visible, mind. It would take some specialized cameras to actually get a good look at them. But, more immediately relevantly, they are very tickly.

Tickly inside of Willow's nose.

Which may result in her sneezing, spraying elemental laden droplets everywhere.

That is, of course, bad.

Hopefully she knows to cover her sneezes. In the event that she sneezes into her hands, she may notice a small number of tiny florescent blue specks.
