This assembly (or ALPHA -_-) is STRONGLY tied to TIMING. I will be brief.
1) Talk to the girl several times DAY, until it becomes possible to build a PLAN- (see Dutch Van Der Linde for a guide on plans ^ _ ^).
2) It is at THIS moment that you need to collect flowers on the street.
3) RETURN to the cave and make a BOMB at the table. The hero will go to sleep.
4) IMMEDIATELY place a bomb on the street.
5) TALK with the girl about ORKS, she will go to call her mother.
6) Hide BEYOND a stone and wait for her.
7) Grab her ...and in fact everything. All these moments are in this order, otherwise you can catch bugs when there are several characters, etc. That is, during the day, collect and apply to the entrance to the cave (hide it), and then it will be possible to enter / exit. BUT it doesn't reach the cave entrance , you can do the trick only with the NOCLIP cheat. And in fact, this is the end of this assembly. Well I never saw again ... Forgive me if I write incomprehensible words .. I'm drunk Х_Х
