To be fair, Link didn't choose to be imprisoned in the transparent encasement but now he had kind of assimilated with it. It didn't bother him at all that he couldn't get out of the case, and he actually felt comfortable at the moment. There were a couple of times when he dozed off as well while watching the final match of the third round.
"I can't believe they won. That Luke Skyrunner is no joke." Link commented as he turned his head towards Satoshi.
On the other hand, Satoshi also got used to Link being in the room. He was tasked with monitoring the berserker so there's nothing he could do about it actually. After all, he's the only one who could easily handle the time bomb that is Link. He was more than elated to know that the final match was over, now he could finally free Link without worrying about his mental state.
