Another possibility is that it's a random act of violence in the context of the story. Jane just happens to be in the wrong place at the wrong time, and a desperate or deranged individual shoots him without any prior connection to him or his cases.
It could be a new criminal that Jane has recently crossed paths with. This criminal might be involved in a high - profile case and sees Jane as the biggest obstacle to their freedom.
Lisbon would probably be the first one to help. She has a deep connection with Jane and cares about his well - being.
It could be a new, inexperienced doctor. Maybe they make a mistake during a surgery that Meredith is involved in, accidentally causing her harm. For example, they might misread a vital sign or use the wrong instrument.
It could be a rival assassin. They might see Kassandra as a threat to their own reputation or contracts.
It could be a Sith or a Sith - inspired enemy. They are often the ones causing trouble for the Jedi, and shooting Ahsoka would be a way to strike at the Jedi Order.
It could be Danzo. He has always been a bit of a shadowy figure with his own motives in the Naruto series. He might see Naruto as a threat to his power and influence within the village and engineer a situation where Naruto is executed.
Maybe some of the more conservative village elders. They have always been a bit wary of Naruto because of the Nine - Tails inside him. So they might be behind his capture in the fanfiction.
It could be Madara Uchiha. He was always seeking power and new ways to achieve his goals. Turning Naruto into a weapon would be a great advantage for him in his plans to reshape the ninja world.
It could be the students. They might think Snape is too gloomy and old - fashioned in his appearance. So, as a bit of mischief or maybe out of kindness, they use their magic skills to give him a makeover. For example, Harry Potter and his friends could be behind it, using spells they learned in their Defense Against the Dark Arts class.
There's also a possibility that it's an accident. In the chaos of a battle or a tense situation, a stray bullet from either side could hit Katniss, even if no one actually intended to harm her directly.
Lisbon could be a top contender as a savior. She knows Jane very well and is highly motivated to rescue him. Her detective skills and knowledge of Jane's habits would be very useful in tracking him down. Another could be Cho. He's very resourceful and has a calm head under pressure, which would be great for handling the situation.
