Just came across this. Why does Scarlett have the other USB?
I saw this the first time the scene was shown (once I got done trying to peek down Scarlett's cleavage), so that we would know where the other USB would be but MC needs to figure it out in the story.
As to why, there are a couple of reasons I can think of:
1. MC gets the USB drive later in the story from someone in 1999 and Scarlett in the past is the girl other than Jenny that MC has gotten the closest to (and by my mental tally has had the most sex with). Jenny would be the most trusted to keep it but she's not around to keep it safe so he gives it to Scarlett, and she puts it in her keepsake box with other items related to MC.
2. Alternately, April got the USB drive from MC's dad in 1999 or sometime before the accident and gave it to her sister for safekeeping. Maybe the mix tapes/CD were also gifts from her sister and that's why they are in the box with MC's photos and other memorabilia from that period.
3. Another option is that masky appears to Scarlett in the past convincing her that he's MC (or his dad if that's who he is) telling her to keep it safe and hidden knowing that she would be around in 2019. MC has a relationship to her through her daughters, giving him a way to retrieve the USB drive at the right time.
4. Last one is that Asuka and Scarlett are both redheads and the universe requires them all to be together in order to keep things in quantum balance.
