Loki blinked. Now that was a curious question. Especially since he wasn't really the type to sit still ever. Things had changed now to an extent, but he was still almost always moving. Whether it be turning his head, stretching his hands or wiggling his feet... he moved. Unless he was sleeping, because then he didn't move much at all. He just, as a general rule, had far too much energy that he had to do something with it. No, if Loki sat still, there was a good reason for it.
He gave Sigyn a look to say, “don't you know me at all?” But didn't say anything along those lines. Instead he let his normally dour and blank expression stay off his face as he asked, “why?”
Looking from the bowl, to the part of the snake he could see beyond it, to Sigyn and back between the three, Loki thought he had an idea of where she was going with such a question, but wanted to hear it from her.
And while he would love to hear that she was going to bash the snake's head in with her bowl, Loki knew that unlikely. He was suspecting that she would want him to balance it somehow, the bowl, until she got back. Something the Trickster wasn't entirely sure he could manage. What if he coughed.... which was common enough with his dry mouth and throat? What if he sneezed? Would he not only have to endure the dripping then, but also the spilled venom from the bowl?
That was a risk he was just going to have to take. “As long as I have to.”
