Reina and Koharu were talking about buying gifts and treats to each other in "Turn Dori Chicken" segment.
Chicken - So you bought anything for Koharu?
Reina - NOPE!
Koharu - *cry*
Chicken - But you are her senpai?
Reina - Yes I'm a senpai but... no!
(note - not exact translation but something like that)
Then afterward Reina talked about her buying gifts to her friends when she went to Hong Kong for the fansclub tour.
Chicken - So you bought Koharu anything (meaning in HK)?
Reina - NOPE!
Koharu - *wa!!!*
Chicken - Why? You don't like Koharu?
Reina - well... perhaps... I wonder...
Caption + Koharu - *!!* (Reina background - joking)
(note - not exact translation but something like that)

There's gonna be alot, I guess I'll post one to two quotes each time for each H!M I have on my HD, then I'll go through other files. Don't want to dig up my DVDs, since that will take too long!

this is the exact translation based on the subs:)
C: You two are the lowest juniors, so have you ever had one of your seniors treat you to something?
R: I have!
R: Aichan or soemone will say "Reina, do you want me to buy this for you?" and I'll say "No, I'm fine!"
R: But then the'll buy it for me anyway.K: That's a bad thing to do!
R: I guess I get them to buy it for me.C: What kind of things have they bought for you?
R: Fruit, tea, that kind of thing.C: What about, Koharu?
K: Never!
C: Never? That's so sad!
*Reina laughs*
R: I'll buy something for you eventually!C: So. Reina, you've never bought anything for her?
R: Nope.*Koharu cries*
C: Why? Isn't she your junior?
R: She is, but... I don't.*Koharu cries*
C: Reina, you're a tightwad!
R: I guess I do get called that a lot.
R: But that's not right!
R: See, earlier, we went to Hong Kong for a fanclub tour.
R: And I bought souveniers for my friends, but none for me.C: What about any for Koharu?
R: None.*Koharu cries*
C: Do you hate Koharu?
