Of course, no matter what she said, it was not okay for a child to fight. So since they concluded that Tie's reaction is because of what her body remembers while she forgot the memories, they decided to not approach Tie anymore (because seeing them will trigger deeep hidden trauma). Agavert decided to disband. Through Lucarion's and Ardiana's conversation, Astier's memory loss is also related to the timeline's misalignment. Timeline will align in 11 years and her body's time will start to flow but it is not sure yet that she'll recover the lost memory. During those 11 years, Astier will remain a 4y.o kid (both mentally & physically). Lucarion also decided to stay away from Tie even though he don't know where to go. The imperial fmily will organize an event 11 yrs from that day in hopes that it is also the day Tie's growth & memories will be back to normal. The banquet is also the celebration of Astier's 4th birthday. It's also the 1st time she'll be introduced to the public. Lucarion is sure Tie won't remember him but Ardiana asked Lucarion to still comeback in 11yrs.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule you will find me in most romantic historical manhwa comment sections
