• This article explores a sequence organizational phenomenon that results from the use of a loosely specifiable turn format (viz., That's + wh-clause) for launching (next) sequences while at the same time connecting back to a prior turn. Using this practice creates a sequential juncture, i.e., a pivot-like nexus between one sequence and a next. In third position, such junctures serve to accomplish seamless sequential transitions from one sequence into a next by presenting the latter as locally occasioned. The practice may, however, also be deployed in second position to launch actions that have not been made relevant or provided for by the preceding action and exhibit response relevance themselves. The sequential junctures then become retro-sequential in character: They transform the projected trajectory of the sequence in progress and create interlocking sequential structures. These findings highlight that sequence is practice, while pointing to understudied interconnections between tying and sequentiality. Data are in English.
