Sorry if this has already been discussed, but I just had an epiphany!
The Captain = SLE
Maria = IEI
Note also how he softens under her influence! It's the pings of Fe!!
I get it now!!!
EDIT (12/26/2010): please disregard this thread--it was made back exactly one year ago (WOW!), when i was a newb and my understanding of socionics was TOTALLY off. At the time I thought i was IEI (even though i'm really IEE). Which explains why i thought Maria was IEI (she is actually the same type as me). And thus why I related so much to the Captain to call him her dual.
