I hope Rikka doesn't change into something she isn't....She doesn't seem to be running from reality, rather she knows it and although her chuuni behaviour is something she uses to cope with that fact, she seems to be a fantasist at heart. Her suddenly trying to turn riajuu would be extremely strained and unnatural.
On another note, Dekomori was great this ep....can't stop equating her to Nonna and that Katyusha scene though
