That's fine, the more important thing is that Helena survives. Visibility is a bitch to lose, more so if you're actually use to having it, so if need by don't hesitant to go to Annabeth. She'll make sure Helena has a quick escape and someone to cover for her, and Annabeth can continue to do her archery thing or at least get her to the college where she'd be safely out of danger. It'd also introduce our characters to each other, so that's a plus.
