Hearing that make him grins, not out of amusement but a sense of responsibility to make her feel better. He doesn't want her to constantly worry about him although he knows with the knowledge of the network and Numbered, that's no longer possible. He will still try nonetheless. "I will." To do any less was tantamount to betraying her trust in him. Unlike Melissa who was strong and capable of taking care of herself, Celia is someone who needs to be taken care of because of her sheltered upbringing. As a friend, some of that responsibility fall on his shoulders.

Taking another sip of the coffee, he considers his option in what to tell her. Much of the things related to the Gundams are still top secret and he's not about to risk an investigation by the FBI if he somehow disclosed something by accident.

So instead, he goes for something harmless, "My name..." well, it would only be fair since he knew hers now, "...was Tieria Erde."
