Relationship between type 2 and type 5

The altruistic and the observer

Elena Gilbert (The Vampire Diaries)
Sherlock Holmes (Sherlock)

Attraction

These two types are opposed on many points and can be complementary.
The 2 is attracted by the intelligence, the self-confidence and the calm of the 5. His emotional detachment can also intrigue him.
The 5 is attracted by the optimism, the kindness, and the goodness of the 2. As well as his social ease.
It is often the 2 who initiates this relationship because he can find it as a challenge to please the 5, and as it can be complicated, it can make the 2 even more determined.

Points where to be careful

The 2 may feel hurt, frustrated and neglected by the 5 if he is giving full attention to his mental world without paying any attention to the 2.
The 2 needs proximity, while the 5 needs a lot of personal space, it can create a lot of problems if they can not find a balance that really suits them both.
The 2, under the influence of his compulsion, can become too obsessive in search of the attention of 5, which can frighten him and make him run away.
