[Hayley tugs the sweater-wrapped bundle from her bag and hands it over to him, sweater and all. She wonders if Bruce could recognize Tony's handiwork in the lead box that houses the Kryptonite and does her best to explain quickly, still both hurried and afraid.]

You can unwrap it, but do not open the box. And don't mention it to anyone until we talk. [She pointedly meets his gaze, because she knows how close he and Tony are.] Anyone.

[Then she's glancing at her watch, closing her bag, and trying as best she can to reclaim her normal breathing rate.] I'll be there. Tonight. Thanks.
