Cass usually feels as if she is good at things. Not everything. Obviously. But the things she usually has to do. She is good at stealth. She is very good at combat. She can use most any weapon she is handed. She is good at detective work. She is observant and has, generally, good instincts.

Socially, too, she has been improving, even if she still sometimes isn't the best at communicating. She has made friends. She feels accepted into her family. She has felt... moderately competent at supporting her family in the ways they might need support that do not relate to combat or athletic activities. Cass is, she hopes, a good friend. A good daughter. And a good sibling.

And it's that last one that has her stuck now, isn't it? Because she has a new sibling. And there has been a minor emergency, and Alfred had to step out to help Bruce handle it. And that means that her new sibling has been left without adult supervision. Not exactly an unheard of situation for much of this family - few of them had had ideal childhoods with caring parents - but, obviously, that's one of the things Bruce tries to do differently for them all now, isn't it?

And Cass is an adult. And in the Manor. And a good sibling. So, naturally, she is perfectly willing to do some babysitting. ...The only problem? Cass isn't entirely sure that she is good with kids.

She hasn't been around many. Only Damian, really, and he is no more a 'normal' child than she was. Rumor has it she was in fact a child herself once but, well. Her experience was far from normal, wasn't it? Suffice to say, following her own caretakers' examples of how to treat a child is not an option.

Nervous? No! ...Not exactly. ...Maybe yes. Cass wants to be a good sister, and this is a great chance to get to know her newest sibling! But also, responsibility. And she wants to do it right.

She peeks into the room the child had been left to play in, and tries to project absolutely none of the nervousness. "Hello."
