This just occurred to me on rewatching Hitman: Agent 47.
Katia’s mom is sent to the right as she is shot, which means her killer fired in from the left. When you see tiny!47 running up to the car, he runs in from the right. Therefore, 47 did not shoot Katia’s mom as we had previously believed.
So I am going to propose to you a new and possibly even more angst-ridden theory: 47 was trying to stop the killing because he knew it was going to happen, but he got there too late to be of much help, but he still wanted to make sure Katia was OK.
Now has two attachment points:
1. tiny!47 looks to be about six to eight; tiny!Katia seems about three or 4
2. 47 stated that Katia’s real name is “Quatre-vignt-dix”, rather than just plain old “90″, so I’m thinking maybe that was how she was actually dubbed in the lab and a lot of people just shortened it to “Quatre”, which Katia probably stumbled over when she was found after Litvenko fled (or the other person she was talking to misheard/thought she sneezed/whatever) and we ended up with Katia van Dees
