I thought about it before, maybe even mentioned it. But Expat's asking LII's about Fe dual seeking reminded me:
ISFp + ISTp & ISTj + ISFj - What is Ne to you?
ESFp + ESTp & ESTj + ESFj - What is Ni to you?
INTp + INFp & INFj + INTj - What is Se to you?
ENTp + ENFp & ENFj + ENTj - What is Si to you?
ISTj + INTj & INTp + ISTp - What is Fe to you?
ESTj + ENTj & ENTp + ESTp - What is Fi to you?
ISFj + INFj & INFp + ISFp - What is Te to you?
ESFj + ENFj & ENFp + ESFp - What is Ti to you?
