"tesu" shares with "tehu" the ability to be used at the end of the first clause in a sequence of clauses, and also carries a similar meaning of incompletion; in addition, it encodes the expectation that the event referred to by the first clause should have happened by the event(s) of the following clauses. This expectation does not need to have actually been fulfilled; the breakfast that was expected to be cooked in the first clause of (24) was, in reality, never cooked due to the ensuing eruption.
