Gaz has finally decided to show Zim how much she really cares about him, even though she hated showing it she thought that maybe it woudn't hurt to show kindness once in a while. so first thing she does to prove her 사랑 is 키스 her Irken lover.
I didn't find the 컵 케이크, 컵 케익, 컵 케 익 the heartwarming part. I thought it was the part where Zim let's 지르 off the hook and doesn't get mad was a rare instant where it showed that, in his own way, Zim cares for Gir.
