The embarrassment is starting to fade into anger since one, he's acting like she did some horrible crime (he's a king; maybe she did), and two, he's very clearly bossing her around (he's a king; it's literally his job), and that's something of an unfortunate trigger for her.

Thankfully, she's currently just staring a little, she hasn't gotten to the point of needing to yell.

"I poked you," she protests, looking baffled. "Would you have freaked out too if I poked you with my finger? It's pretty much the same thing. Less dangerous, even, because the tentacles can't grab you."
