Follow Nina some more

You decide to wait for Nina outside the store after 10 minutes she gets out. She walks towards the bus again and gets on again.

You start to follow her with your car. And you are surprised she doesn't get out at her house but at an earlier stop.

You see how Nina walks out of the car and you start to park your car and jump out of it. You then follow Nina.

You see how she things the bell at an apartment block and she takes the stairs a couple floors upwards.

You keep following her and see how Nina enters one of the apartments. You can't see who let's her in though.
