If you are talking about the movement inside of the lab than all you have to do is this:

1: Once you reach the dig site while it is raining, stop right before the loading zone of the cutscene 2: Slowly move towards the cutscene while spamming the options menu 3: If you do it right, you should have the options pulled up during the cutscene 4: Click "Get Unstuck" which will leave u with the text and back at your house 5: Slowly start clicking and walking at the same time towards the lab but make sure you don't finish the dialogue 6: Once your Dad says, "See you later" all you have to do is stand in front of the lab door, click and then quickly walk in

If you do this right you should have the camera zoom out before you enter the lab which means you successfully did it. From now on, you go grab the potions in the box and finish the dialogue from your parents which then it will cut to the battle with your Mom.
