Normally Groot would give some attitude about not caring and not being at all interested. But that wasn't true this time. He did care and he was very much interested. "I'm Groot," he offered, sitting down in front of her, big eyes looking up at her. "You look different now. Why?"
He'd felt like they were more alike when she'd looked more like he did. But there was still that sense, that feeling, that she was still similar and that was good enough this time. Because he'd seen with his own eyes.
And she'd been nice to him when he'd really needed someone to be nice to him. The only time. Usually he fought off niceness.
