Final answer:
The repeated use of "my son" by Julian during Frank's introduction emphasizes their familial bond and Frank's elevated status. It reflects Julian's pride and may use traditional connotations of prestige associated with paternal relationships to underscore superiority.
Step-by-step explanation:
Julian repetitively refers to Frank as "my son" during the introduction to emphasize the pride he feels and the close relationship he shares with Frank. This form of repetition serves to highlight Frank's elevated status and signals a sense of superiority attached to being Julian's son. There are various ways in which language can underscore someone's status; in the case of Julian's introduction of Frank, it is likely that along with the repetition, the tone of voice, choice of words, and context of the accolades and accomplishments he might mention, also serve to elevate Frank's status in the eyes of others. Furthermore, repeating "my son" could be highly effective in emphasizing superiority because it reinforces the familial connection and the lineage which might carry its own prestige.
The concept of a father figure presenting his son or offspring in a manner that exudes superiority is not unique and can be found in many cultural and historical contexts, such as a powerful male leader being viewed as a father to his people. By repeatedly affirming his paternal relationship with Frank, Julian could be using a traditional expression of pride and legitimacy to both broadcast Frank's stature and perhaps his own.
