Ne as a function isn't the most extraverted anyway, that would be Se territory because of the tangible properties and forces it deals with. In short: Ne-Te works well. Se-Ni, however, is a more extreme combination among subtype pairing. SLE-Se/IEI-Ni duality has the greatest discrepancy in respective externality/internality.
To me, Aggressor-Victim relations depend on energy exchange more than Infantile-Caregiver duals.
