I never killed the adoring fan. If he's too annoying, just send him back to the arena district.
I agree. In my mind, the adoring fan is a very skillful enigma purposely placed in Oblivion by the Beth.. He is un-attractive, annoying and of very little use in assisting you with your goals. However, he is one of the few NPC's in the game that truly admires you for "you," and not what he can gain from a potential friendship. With the dearth of companions available in the game (especially those that actually like you), my characters normally welcome his friendship and company. Unfortunately, my first character did accidentally kill him. He died while exploring a cave with her, and then re-spawned when she was deep within the nether tunnels of Oblivion. She lovingly looked at him with a tear in her eye knowing that even her awesome skills could never get him out of there alive. She was right and he died "permanently" in that gate; in that game.
My second character is much more careful with him. She does cut his annoying speech off. He only manages to get a few words out when they talk.
1. By Azura,......... cut off.
2. Yes!,....... cut off.
3. Here?.... cut off.
He is only allowed to accompany her when she conducts business with vendors/guilds and on strolls to collect alchemy ingredients. She fervently protects him from wild life during any attacks on these expeditions. She got totally pissed with him when she spent time and money reverse pickpocketing zero weighted attire that was more visually appealing, and carefully enchanted with shield and reflect damage. He dissapeared (ran away) once after a bear attacked picking flowers, and returned with the expensive enchanted attire missing. Since then, he has to wait patiently for his grand champion in her Choral home or wizard's tower while she is vanquishing evil. But, she would never intentionally kill him. She would simply dismiss him first.
