Granted, if you read them without thinking about it, you'd probably react with a laugh or use it as ammunition against Bungie, but quite awhile back, I did think about it for a little bit, and realized that her lines are so logical it's almost scary. Here's an example of something I found; you can say her "no time to explain" line on a loop: I don't have time to explain why I don't have time to explain, why I don't have time to explain, why I don't have time to explain, why I don't have time to explain... Et cetera. Personally, I think this is the reason Bungie put the line into the game, even though it would be interesting to know more about her. Please put your own ideas in the comments below! I will give credit if I decide to put it in the main body-text. TL;DR You can put the Stranger's line on a loop: I don't have time to explain why I don't have time to explain, why I don't have time to explain, why I don't have time to explain, why I don't have time to explain...
