On the other hand, he could use it as motivation. He would be determined to prove everyone wrong and show that he is a valuable asset to the team. So he would work even harder, albeit in a more cautious way to avoid further false accusations.
Maybe the higher - ups misjudged him. They could have been influenced by false information or just had a pre - conceived bias against Tony. For example, if there was a case where evidence was planted to make it seem like Tony made a mistake, and the superiors didn't bother to dig deeper.
Another idea is that Tony is injured while rescuing a kidnapped child. He gets stabbed in the process. His injury makes the NCIS team more determined to catch the kidnapper. During his recovery, Tony forms a special bond with the rescued child, which is a new and heart - warming aspect of the fanfiction.
Abby would be all over Tony, bringing him some of her special energy drinks (even though they might not be the best for a sick person). She'd also use her skills to try and find out what's wrong with him in a more scientific way. Ducky would of course offer his medical expertise, and might even tell some long - winded stories while examining Tony to try and keep his spirits up.
He might be initially in shock. Percy has been through a lot with Annabeth, so being dumped would come as a huge blow. He could be speechless for a while, unable to process what has just happened.
He might be shocked at first. Naruto is used to seeing Kurenai as an ally, so being hurt by her would be unexpected. He could immediately ask her why she did it. If it was a serious injury, he might struggle to stay conscious while trying to understand the situation.
Well, Sirius could get really flustered. It could lead to some comical or tense moments depending on the context of the fanfiction. The howler might reveal something he doesn't want others to know.
He might initially be in disbelief. Natsu is used to the loyalty among his Fairy Tail comrades, so betrayal would be a shock to him.
If his friends continue to ignore him, Harry could become sad and withdrawn himself. He might start to isolate more, spending time alone in places like the Forbidden Forest or an empty classroom. He might also lose his confidence in himself, thinking that he is not worthy of their friendship. In his loneliness, he could focus more on his studies or some solitary magical pursuits, trying to distract himself from the pain of being ignored.
He might be annoyed. After all, being stuck doing something you don't want to do is not pleasant.
Well, he might be really flustered. Percy is often portrayed as a bit of a goof in some fanfictions. He could stutter and turn red, not really knowing how to handle the situation.
