In terms of the overall plot, it could lead to a race against time. The characters will need to find a way to exorcise Vecna from Will quickly. This might involve seeking out new knowledge, perhaps from an unexpected source. Maybe an old character from the past who has some knowledge about Vecna's possession returns to help. It also opens up the possibility for new alliances and betrayals within the group as they struggle with this new situation.
However, it could also be a turning point. If Gohan realizes that his anger is misdirected or if he communicates his reasons for being angry to Videl, it could strengthen their relationship. They could learn more about each other's boundaries and grow closer as a result.
The injury could introduce new characters. Maybe a healer Wesen shows up to help Nick. This new character could bring in new plot elements and relationships. Also, it might change Nick's perspective on his role as a Grimm. He could start to question if he's putting himself in too much danger and how it affects those around him. This internal conflict can drive the storyline in different directions.

His injury can have a big impact on the story. It might make Hiccup question his own abilities. If he gets seriously hurt, he could start to doubt if he's cut out for all the dangerous things he does. This internal struggle can be a major part of the story. Also, it could affect how the village views him. They might see him as more human and less of an invincible hero, which changes the way they interact with him and support him in future challenges.
If Tai gets hurt, it can have a big impact on the group dynamic. The other characters may become more cautious in their actions, fearing that the same could happen to them. Some might become overprotective of Tai during his recovery. His injury could also bring out different sides of the other characters. For example, a normally timid character might become more assertive in finding a way to help Tai get better. And his friends would be more united in their determination to get him back to full health, which could strengthen their bonds.
