Your brothers were out on a mission again, doing who knows what while Splinter and April tried to find the right weapon for her. And you decided to check in to see how the process was going.

Only to see him give her a tessen. And say that he'd give it to his daughter if she was still with him.

You had been just about to enter the room when you heard the exchange. You froze before hesitating and then walking away. It wasn't like you cared it just.. wasn't fair that April got the tessen when you were his actual daughter.

You tried to forget about it though and that's how you got here. Trying to distract yourself while you waited for your brothers to come back to the lair.
