One thing you missed - It was Karma's dream, and it all had one person in common... Amy.. maybe for the first time, even if it was just a dream, which usually projects your thoughts about some issue, Karma was thinking about Amy in a completely different way. They didn't had to spoil more with this, second part of the season will pick this up i'm sure of it.
Btw, for anybody interested, last night episode got 891k viewers, with 0.4 rating in P18-49, and 1.26 in F12-34. (second most watched show in that demo, Awkward being the first with 1.46). Episode was up by 50k viewers from last week.
Statistically, Season 1 had 950k viewers in average, while 10 episodes of Season 2 had 790k viewers per episode, which is decrease of 16k viewers, yet considering it was aired in fall, when competition is strongest, its performance was quite stable.
