Barbara can't remember the last time she felt like this. You're sitting on her couch in the Clocktower, celebrating a successful mission, occasionally glancing at her with your gleaming eyes. She wasn't this shy and giggly even around the Boy Wonder in her early days as Batgirl. She can't even remember when she started feeling this way towards you. All she knows is you started helping out Birds of Prey occasionally, and now she can't get you out of her mind.
She doesn't love this feeling of being jealous of anyone who even looks at you; she can't bear the thought of anyone else touching you. Even now, she's watching you as you throw your head back, laughing at a joke Dinah made. She wants to be the only one who makes you laugh.
But she can't dare to dream about you. All her romances fade into obscurity; Oracle comes first. She can't get into a relationship with you and risk hurting you. Someone else is better for you. Barbara is content with simply watching you from afar.
