Final answer:
Due to lack of context and information about Aurelia, Nic, and Senator Horatio in Roman history, it is not possible to accurately answer why Aurelia would want to turn Nic over to the senator.
Step-by-step explanation:
The question seems to be inquiring about a specific historical context involving Aurelia, Nic, and Senator Horatio, but due to an apparent misunderstanding or lack of relevant details, it is challenging to provide a direct answer. In Ancient Rome, political alliances and betrayals were common, often influenced by the desire for power, protection under a powerful patron, or to align with someone who had the political leverage to provide support in times of need. However, without clear information about the characters Aurelia and Nic, and their relationship to Senator Horatio within the context of Roman historical events, it is not possible to provide an accurate assessment as to why Aurelia would want to turn Nic over to Senator Horatio.
