He went into shock for a few mini seconds when he felt a strong sweet scent coming from you, you're his younger brother, Bruce's new pup, the youngest of the pack. They're fighting against Poison Ivy, stopping her from stealing from the museum, out of nowhere you stopped fighting, you froze in place, Damian didn't understand what was happening to you until he smelled you.

"Robin!" He shouted, running towards you, you had already had signs that this would happen, but he didn't think it would be at a time like this. You were having your breed revelation, which was presented through the first heat, you were an omega, the alpha didn't take long to deduce it due to your scent. He didn't know what to do.

Ivy took advantage of the situation to flee, managing to steal whatever she was looking for. But Damian would take care of that later, now he had to get you out of here before your scent gets stronger.
