Zane might start by assessing the situation. If they're in a dangerous place, he'd be very cautious. He could also be a bit impatient with Syrus at times, but still try to keep him safe. For example, if they're in a dungeon - like area in the Duel Academy, Zane would quickly find a way out, pulling Syrus along if he has to.
In the Yu - Gi - Oh fanfiction, Zane could initially be frustrated with being stuck with Syrus. However, as time goes on, he might see it as an opportunity to bond with his younger brother - like figure. He could teach Syrus how to better read opponents during a duel, how to predict their moves. Zane may also encourage Syrus to be more confident in himself and his dueling abilities. This could lead to a significant transformation in Syrus as a duelist, all because of the time they're stuck together.
In the Yu - Gi - Oh fanfiction, when Zane gets stuck with Syrus, they might have an intense duel training session. Zane could be super strict with Syrus, pushing him to improve his dueling skills. Maybe Zane would share some of his top - secret dueling strategies that he's developed over the years.
In a Yu - Gi - Oh GX fanfiction, Zane could be hurt because of his own over - confidence. He might attempt a really risky move in a duel, thinking he can handle it, but it backfires. This could lead to him getting injured, like his Duel Disk malfunctioning and giving him an electric shock. His pride would take a hit as well as his physical state.
It could be that Camila tricks Syrus into going to a dangerous part of the Duel Academy grounds. Maybe she sets up a trap there, like a collapsing structure or some sort of magical device that activates when he steps in the wrong place, and as a result, Syrus gets injured.
Maybe someone forced him to. For example, a friend who is a big Syrus fan might have put it on and made Zane stay and watch.
His anger might lead to him making rash decisions. For example, he could challenge someone to a duel without fully thinking it through, which could then create more conflict in the story.
At first, their relationship might become strained. Zane's anger could make Syrus confused and a bit scared. Syrus might try to avoid Zane, not knowing how to deal with his anger.
Maybe Zane and Syrus get trapped in a strange virtual world created by some glitch in the digital system. They have to rely on each other's skills to find a way out. Zane's logical thinking and Syrus's knowledge of the digital realm might be combined to overcome the various obstacles like malfunctioning programs and security barriers.
The main characters are clearly Zane and Syrus.
Another possibility is that Camila is being controlled by a more malevolent force. This force wants to disrupt the harmony at Duel Academy, and Syrus, being a key part of the group of friends, is targeted. The injury could be a way to start a chain of events that would lead to chaos and drama among the students, which would make for an interesting plot in the fanfiction.
He might be really bored or annoyed at first. Maybe he'll roll his eyes a lot and keep thinking about how he got into this situation.
