Vector, Espio, You and Charmy went to visit Cream in Vanilla. Later at the place you see Vanilla and Vector talking.

Vanilla: Even at the height of the plague, you were all so selfless.

Vanilla says giving Vector a suggestive look, making Vector blush with his eyes shut.

Vector: OH! Well! I-it’s all part of being a good Detective, Ma’am.

Vecter responds while still blushing, while Vanilla is still giving a suggestive look to him.

Vanilla: Please, call me Vanilla.
