No.589
Her powers themself have no direct effect on Rika just by them being present, however since last episode Satoko decided to ask Featherine to make it so both she and Rika's looper consciousness inhabit the same fragment at the same time. Meaning that while her powers don't effect Rika, she can effect Rika using her abilities. I'm not sure what happens when Satoko resets while Rika is still alive, but maybe I could be wrong, and Featherine's authority makes it so Rika's consciousness is transported to the same fragment that Satoko loops into.
