IS DEAN WINCHESTER REALLY IN LOVE WITH CASTIEL?
From an article named "How to learn reading men through their body language" - By Dr. Alicia Fernandez-Sexologiist - Clinic of Human Sexuality and President of Puerto Rican Association of Education, Counseling and Sex Therapy- There is a way to silently discover what a man feels for another person through his body language. According to the expert, the gestures and postures are an excellent way to discover if he is looking at you or if you are simply cheating yourself. Emotions, thoughts and personality, end up being reflected in the gestures, the look and the posture. Hence, it is said that nonverbal language can not be hidden and it does not lie.
A parallelism between the ten attraction signs which are mentioned by Dr. Fernandez and Dean Winchester`s behavior in front of Cas.
1. He slightly raises his eyebrows â it means he finds you attractiveÂ
 2.He separates his lips when he is looking at you â it means he likes you from the first moment.
3. Â He sits in front of you and opens his legs â it means he is offering himselfÂ
OK! the last one is Cockles but WTF!!!!
4. He gently touches his face while he looks at you â it means he is insinuating he wants to kiss you
5. He separates himself from his group and watches you from a distance â it means he is asking directly for your attention
6.  He scans your whole body â it means  he wants you
7. He looks at your face in a triangle-shaped path, first your eyes and then your mouth â it means he likes what he is seeing
.8. he helps you with your clothes (tie is ok too)- it means he is seducing you directly
9. he puts his arm on your shoulder or waist. It means he wants to lead you you
10. he puts his jacket (or a blanket in this case is the same) on your shoulders. It means he is protecting you and at the same time he keeps your smell in his clothes
A plus... He licks his lips watching you ;) But I think I do not need adding anything else because his body talks for himself
