Does Serena's Feniken evolving mean something?

Well I compared it to Torchic evolving, which is a symbol of May's development and her student teacher relationship with Ash. May was an inexperienced trainer at first. As she became more experienced, Torchic evolved into Combusken. She brought it to Kanto with her. When it evolved into Blaziken, at around the end it fought on equal footing with Ash's Sceptile that it led to a tie. Meaning the student is on equal power with the teacher. But it remains to be seen if Braixen evolves into Delphox, if it it means something else entirely.
