Lara is right.
Step-by-step explanation:
We are all aware that many person gets lost amidst the dense forests and that too in winter not to mention the nerve cracking chillness. When Lara and Lars finds a dog with the Brandy that itself proves that they are really lucky mascots.
They should be brilliant enough to use the Brandy to start a fire and send an SOS to the eagle eyed Forest rangers. Lighting fire would be a brilliant idea as it would draw the attention of the life savers and to locate them easily through the smoke.
If Brandy consumed to keep them warm it’s just a temporary solution to keep the body warm. But after an hour it tranquilizes the brain and they might become a prey to the forest animals or even lost forever.
