Okay you got me!
I guess if I had to choose it would be tenkan, followed by irimi.
Getting off the line and getting to the backside of your opponent is the most common thing to do in a "generic" situation.
from there, iriminage would probably be likely technique that would develop.
However, philosopically, you really don't know what may happen so I submit that "no mind" must exist before any physical technique, hence my initial response!
