In Annual #2, there's a flashback to Dick's time as Robin showing him working with Batgirl (Barbara Gordon). They get knocked unconscious by Crazy Quilt and wake up stuffed together inside a safe. Batgirl is dressed, you know, as she usually is, and there's a lot of contact going on. Batman comes along and cuts a whole in the safe to let them out. Robin gets out hunched over and holding his cape in front of him. Batman notices.
