Obi - Wan might be shocked at first. His eyes would widen and he'd quickly try to assess Anakin's condition, checking for any visible wounds.
Obi - Wan may also experience a range of emotions such as guilt. He could think that he should have been there to protect Anakin better. He would then focus on getting Anakin to safety, perhaps carrying him to a nearby shelter or medical facility while whispering words of reassurance to his unconscious friend.
In the fanfiction, it might be that Anakin has been poisoned. As the poison takes effect, he collapses into Obi - Wan's arms. Or perhaps Anakin has just learned some devastating truth about his past or the Jedi Order that shocks him to the point of physical collapse.
Perhaps Obi - Wan uses his Jedi skills in a creative way. For example, he could use a Force - related technique that shields Anakin from the influence of the Sith. He might create a sort of Force barrier around Anakin's mind, preventing the dark whispers from corrupting him further.
In many fanfictions, Obi - Wan might use his deep knowledge of the Force. He could reach out to Anakin through a Force - bond, calming his inner turmoil and guiding him away from the dark side. For example, he might remind Anakin of their past together, their training, and the values they once held dear.
Maybe the Force itself could be an antagonist in a sense. The light side of the Force would be trying to pull Obi - Wan back from the dark side. And the natural balance of the Force that doesn't want too much dark side influence could be working against Anakin's plan to turn Obi - Wan. So the Force, in its own way, could be the main antagonist.
The struggle between the light and dark side is also common. Since we know Anakin's fate, fanfictions often play with the idea of Obi - Wan trying to keep Anakin on the path of the light. It's about the internal and external battles they face in relation to the Force.
