RE: They were a husband and wife team. There are no examples of one or the other speaking.
Again, The verb “explain” is PLURAL in the Greek indicating that BOTH Priscilla and Aquila were involved in teaching Apollos.
I needed to more specific:
There is no actual conversation showing one speaking, then the other, as is shown a few verses later, where Paul is shown conversing with the certain disciples in Ephesus.
