ESTj (Te) + INFj (Fi) - a reserved couple
How would you describe this couple? Do you know any?
I only know one real delta rational dual couple, and she might be Fi and he might be Si or Te or no subtype. They definitely have a subtleness about them.
What I am commenting on is a faulty paradigm that there are two parts to each couple - the very reserved I type, and the very outgoing and talkative E type. It seems in this situation there would be a mutual reticence....

In ER, there was a fictional couple which consisted of Samantha and Luka... (LSE and EII) They were duals which couldn't connect each other because of communication problems. In fact, Samantha accused Luka to be passive-aggressive.
