Quick as she is, she temporarily loses sight of Tom as he leads her through the halls and so she must slow her pace some. This gives her caution, elevates her hunter's instincts as she treads lightly on his trail. Her slowed speed gives enough time for Albert to catch up to her, though she doesn't say a word as they continue after Tom. Moments later, they'll wind up rounding that corner to face the enemy. Felicity's knife is at the ready.
