Phasma's nod gave allowed him to relax once more, that he was allowed to express his needs and be heard meant a lot. It also gave Noah comfort that they'd figure their way through the complex decisions that lay ahead and just thinking about some of that made his head hurt. The milestones that led to Stiles turning 21 were too many and too varied to mention and here he was starting the journey one more time. Yikes.
Noah gave a chuckle at her phraseology. "He's that, alright," he replied smiling knowingly. "Excitable's the least of it, I'm afraid," he said with a nod, "and yes, he gets that from me.

"You guys are officially family now. Good luck with that," he teased.

"Have you had your first scan yet?" he asked Phasma, curious to know how far she'd gotten into the whole process. Clearly not too far. "Maybe I should ask Melissa to make an appointment for you at the clinic," Noah suggested. "She'd be able to help you work out what medication and..." Noah stopped in his tracks. "I'm sorry," he said sheepishly. "I want to be as involved as possible, but we're discussing your body and you know how best to take care of it."
