Alex knows exactly what Natasha's heard, but rather than admit it, she crosses her arms and looks away, still trying to be casual. She ignores Natasha's glance at the notebook - as long as the vampire doesn't reach for it, she'll just leave it there, looking like a totally casual notebook casually sitting on the table.

"I don't know what you mean," she says as she looks back at Natasha, casually making eye contact. She's definitely not going to admit to an assassination plot to someone she met on the bus one time.
