Escape From The Mall is the thirty first story arc in EGS:NP. It started with EGS:NP Comic for 2016-09-16 and ended with EGS:NP Comic for 2016-10-14. It's canon and it features Catalina Bobcat and Rhoda.
Both before and after Catalina and Rhoda talks about what Rhoda already found about her spell.
Catalina casts her new spell when Rhoda cuddles to her, but nobody will notice right away due to change blindness. Until Catalina touches her tail. They (mostly Catalina) decide that trying to disenchant Catalina would be too risky and they need to escape the mall (title drop) first. The story arc ends with them abandoning the first attempt of basically not attracting attention after noticing group of anime and manga fans.
