Istredd studies the turtle and then decides to show it some affection as well. He is not as comfortable as Jack to pet his chin, but he does gently touch its head. A little pat. He is not good at this, but he tries. Compassionate, yes, physical, no. He is far more interested in what Jack is saying, his eyebrows furrowing.

"It doesn't sound like taking drugs is the right move to make with your experiences, especially not if you're prone to sleepwalking." AKA he heard from Lucifer what happened. Istredd was gone most of the first day only to get an update from his roommate later. Drugs have their place in his world too, in fact they're everywhere as more medicinal herbs type of options. Istredd knows how to make many potions that could be drug-like. He just wouldn't necessarily do it for an unsettled mind.

"You must be careful, Jack."
