The b
1-c2 slur probably originates from a later completion of the manuscripts' notation, which is indicated by a comparison with analogous b. 122-123. Chopin most likely added a slur here only in [AG] (→GE) and the second time – only in AF (→FE→EE). Such complementary corrections suggest that there was a stage – probably short – in which both autographs were being retouched in parallel.
