Update 3: Srsne v úli

I have again checked this series (at high speed). (Almost) all scenes in ep 6 (pic below) and 7 (pic 1). Few rear views. A girl also had similar bibs with overlapping straps.
At the intro of ep 6 the boy also fall into water but I haven't found it in the series. Not shown the younger boy and woman.
Boy on ladder in ep 6, sitting scenes (also others, incl teen girl) in ep 7.

Main entry, rating 7 (rather 6)
