When the phone first started to ring, Mikaela thought it might be Zuko. She'd sent him a text message earlier, asking him to stop by when he had the chance. She'd thought that maybe he was calling to say he couldn't make it, or that he wasn't going to be over until late, or something. Because really, besides Zuko, who else had her cellphone number? It wasn't as though she gave it to very many people. Frankly, she wouldn't have had one at all if she had a choice, but it was cheaper than owning a landline and a lot more convenient... even if there was always the possibility of it turning into an evil little robot intent on killing her in her sleep or something.
Of course, that was why she kept it in a safe when she was home. No, not a safe place, an actual safe. A fireproof, waterproof, needed her fingerprints to open, safe. Granted it may not be much of a challenge for a Decepticon, but it sure made her feel better.
The only problem was, when the phone started to ring, it took her a minute to answer.
Fortunately, though, she was getting faster, and just before the fourth ring could sound she had the device in her hand and was flipping it open. The number she'd only glanced at in passing but knew it wasn't Zuko's. Although, she supposed, it could be him calling from a payphone because he'd forgotten his own phone back at the Hyperion or something. After all, who else would be calling her?
"Hello?" she said with a hitch of hesitation in her tone after a brief pause. She tried to prepare herself in case it was Sam, or her father, or something along those lines. You never could tell, in a place like this.
