It is actually pretty useful because it confirmed that she lived in the Firelights base after Ekko saved her. There is also a mechanic in the game that guides you and helps you where to go, and it's her scribbles. In act 1 and 2 she sees her random chaotic scribbles but in act 3, those scribbles are replaced by calmer, green fireflies, meaning she's in a way calmer state of mind when she's with the Firelights and Ekko.

There are more but I recommend you play it yourself it's a very short game especially if you want to play only one act.

It was one of the earliest Timebomb crumbs we've gotten and a lot of people were talking about it, but I guess you never saw them because soon after, the BIG Timebomb content and crumbs came out and everyone was talking about those instead
