Honestly, this episode was by far my favorite! (Even though Azusa's wedding dress & Makoto's manly fighting were epic, too)
I mean, Miki's innocent "Yeah, I ate it" was to die for.
Also, I absolutely LOVED the part where Ami goes "I'm counting on you" while sliding on the door like she's dying and then we get to hear Ritsuko in the background "I'm going to leave you, Ami!" X'D
At first, I really thought the culprit would be Yayoi.
Yup...I guess I'm not sexy enough of a detective...
