EV 42 isn´t her fall I think, we have this pic.
She´s wearing the miko outfit Takeda has been using a lot recently.

Maybe, but given the order of the events and the girls, I stand on Rietta's fall is on 42.
There is a pattern if one take a good look:
Arika: 24, 27, 30 and 33.
Rietta: 25, 28, 31 and 34.
Terena: 26, 29 and 32.
While the pattern is broken on 35 (Arika's bunny event), it's likely only a temporal one and will (possibly) return on EV41.
Also, as it has been said before: there is likely more scenes to Rietta's fall, just like Arika(41) and Terena(43).
