The DJ says Chocolat will be on in 25 minutes, i.e. 21:00 Korean time, 12:00 UTC/GMT, etc.

Ok, so now it's over. I think a lot of the listeners' questions came from the forum that shall not be named , which was a bit weird.
Tia and Melanie talked about the reaction video from the guy who hates Tia and loves Soa. They said it was funny because Tia and Soa often appear one after another in the MV, so it would be "I love you" followed by "I hate you". Tia asked him not to hate her.
Some other stuff:
The members first heard Black Tinkerbell a year ago, but the song was then rewritten and given a faster tempo, so they had to re-record the vocals. All that reworking is why it took so long for them to come back. Because the song has been sped up, it's hard to sing the lines quickly enough and dance at the same time.
The image for Black Tinkerbell was meant to be girly, feminine chic but the some people think the result looks like more like a sexy concept.
The choreography includes kicks and aggressive moves, so they have to stop their skirts billowing up and try to "keep it PG-13" (I think that was Mel). They've asked their stylist to sew the skirts to their shorts, which they've had done before -- Mel helpfully explains this means that they can't go to the toilet for several hours while they're in costume.

The DJ remarked that when they debuted they were famous for having mixed-race members, and they said (as in the article above) that they're tired of being thought of only for that.
When asked what they like to do in their free time, they reply "sleep and eat". Mel says Tia is a bit afraid to go outside, so she dresses up and puts on high heels and dances in front of a mirror in the dorm, even though it's too short to show all her body. Tia hastens to add that if you're a professional dancer you need to wear clothes that will show how your body is moving.
A question about favourite animals leads Mel to say that she wants to have a pet fox and call it Juliane because she thinks Juliane looks like a fox.
One of the listener questions is if someone you didn't know messaged you on Facebook would you block them? They say they try to keep their accounts private and don't use them any more (quelle surprise). Tia says that some people start being rude and acting like anti-fans if she doesn't reply to them quickly, so she has to block them.
There's a question about how they feel now that they've been performing for several years. Mel says they don't feel like seniors because they haven't reached that level (in terms of success and achievement, I'm assuming). She finds it weird when idols who are older than them bow to them.
P.S. They'll be promoting Black Tinkerbell for another couple of weeks,
Tia's favourite American singers are Rihanna and Ciara, and she loves R&B and hip-hop (Rapper T in da house, yo). K-Pop idols she admires for their dancing are Kahi, Jay Park and Melanie is into American teen-pop and Yunho. Demi Lovato and Arianna Grande. The K-Pop singers she most admires are Taeyeon and Ailee, who she met backstage at a TV broadcast shortly before Ailee debuted.
