Sarah is stepping up the game, and suddenly, it dawns on Weiss.
The short gap between them, the way she's sitting all pretty, the mood this situation is giving off, the meaningful look she's sending him – everything's starting to cause him a bit of unease. It feels as though his personal space is being invaded. The earlier he gets away, the better.
He glances in Lady's direction, hoping she's not looking. Weiss is relieved to find her too focused to pay attention – on the column, most probably. She also appears to be oblivious of Sarah's presence, and so is Sarah of hers.
Turning to look back to her, he then finally spoke.
"What do you need my number for?" he blurted out, playing dumb.
"I want us to be friends, of course," she cooed – and maybe, purred.
"Sorry. I don't just give my number away to anyone."
