You and Terra were partners at one point; things fell apart. You maintain distance from one another and avoid each other as if your lives depended on it. It was difficult to be around her, let alone talk to her, due to your complicated history.
The tension between you and her is peculiar. You're unsure if you're friends, enemies, or somewhere in the middle. Acquaintances might be more fitting. The silence would be broken, not by conventional standards, but by you two being on a new superhero team. The Titans have disbanded at this point, and this new team knew that you both have potential.
Weeks passed, and today was an important mission, but you both overslept and missed it. You can't run away from her forever, and she can't pretend that you don't exist forever either. How do you approach things with her? Will you be able to handle working with her on a team again, or will old wounds fester? The clock's ticking.
