Willow is about as angry as Angel and the aliens might not be lucky enough to escape without encountering her. How unfortunate.

For now, though, she nods at Angel. "I-I don't know how many of them there are o-or if there are any others, but... I figured you'd need it and if there are any others, they'd need it, too. So if you want it, I'll just... keep a stash here."

And Angel can come get it whenever he feels like it and keep her as much in or out of the loop as he wants. She really doesn't care at this point and she trusts Angel's judgment, for better or for worse.
