Falling asleep is not unusual; everyone falls asleep.
But not being able to wake up no matter what is strange, which reminded Wen Wen of the sleepers he encountered in Arkham City before. The Black Night Knight is also studying this case, so clearly, this sleep is not simple.
Wen Wen's face darkened. He said he would rescue Delia, but now that she's back, what's the deal with her being constantly asleep?
Moreover, what concerned Wen Wen more was that Delia spent most of her time under his watch. Now that Delia has been hit, it at least means that thing has the capability to act right under Wen Wen's nose.
If such a thing is not restricted, sooner or later it will lead to bigger issues.
He put Delia back into the Sanctuary and said to Jin Kela, "You handle things here; I have other matters to attend to."
After saying that, Wen Wen directly left the Sanctuary. He wanted to see what this inexplicable sleep was all about.
