Mere moments after getting Sunsarity's message Princess Twilight responded to it "Sunsarity I've gotten your message I'm not sure what I can do to separate you or if I even can but you can rest assured that I will try my hardest to do so, me and Spike will be coming through the portal in a few minutes, be sure to tell me where Rarity lives so that I can come to your house,
Signed your friend Princess Twilight."
Anyway Sunsarity sent Princess Twilight another message telling her where Rarity's house was located and she arrived there after stepping through the portal in a very short period of time.
When Twilight arrived at Rarity's house she was greeted by Rarity and Sweetie Belle's parents who led her upstairs to Rarity's room.
Twilight said upon seeing Sunsarity in person "Wow so that's what you look like now."
Spike told both of them at the same time "I don't know I kind of like her this way."
Sunsarity told him "Well I don't, I would like to be separated again."
Twilight then realized as she thought to herself outloud "Wait a minute if those ear rings you're wearing are what combined the two of you into one person then maybe you'll separate if you take them off."
Sunsarity then said "Of course why didn't I think of that?"
Anyway Sunsarity took off her ear rings only for nothing to happen.
Spike then said "Well that didn't work."
Twilight then thought to herself for several minutes before saying "Hmm I know maybe I could try studying these ear rings maybe I can figure out what makes them work and why taking them off didn't separate you."
Sunsarity then asked "How are you going to do that?"
Twilight then told her "I know I'll tell your parents that I'm temporarily going back to Equestria to research this fake illness that Sweetie Belle came up with, I'll even write down notes to make the whole researching your illness thing seem believable, but in reality I'll be figuring out how these ear rings work."
Sunsarity told her "Ok I'll be right here waiting for you to come back."
Twilight then told her "Don't worry I'll be back and so will Spike."
