we don& #39;t talk enough about how smart dean winchester actually is so here& #39;s thread about it
dean created an electromagnet to wipe out the ghostfacer& #39;s hard drive
he made his own sawn off shotgun when he was just a child and he also built EMF reader out of a walkman
he& #39;s very strategic, practical, and clever when it comes to hunting - for instance he drank phoenix ash and tricked eve into biting him in order to poison her
he is actually smart enough to fit in anywhere - when he and sam went to prison he adapted so quickly that he even started his own business there within a few days
