Is Scootaloo related to बनाया गया, एपलजैक, मौजमस्ती ?

In Season 3 / Episode 6: "Sleepless in Ponyville", In the scene, after इंद्रधनुष Dash, finishes telling her 2nd Scary Stories, & just before the group turns in for the 2nd night, right after Rarity tells Sweetie Belle: "Don't worry, u'll be सुरक्षित with me tonight", Scootaloo immediately makes the following statement: "It's not time for bed, is it ?", the only one who reply's to this statement is Applejack, द्वारा replying: "Afraid so, Scootaloo." This seems to imply that बनाया गया, एपलजैक, मौजमस्ती truly is & या related to Scootaloo & this is further displayed in Season 4 / Episode 17: "Somepony to Watch Over Me", in the scene where immediately right after सेब Bloom exits her house window, Sweetie Belle & Scootaloo hide to avoid detection from बनाया गया, एपलजैक, मौजमस्ती entering the room while earlier Sweetie Belle & Scootaloo agree to सेब Bloom that they (Sweetie Belle & Scootaloo) will substitute herself sleeping as "Apple Bloom" in her place, while she (Apple Bloom) is away doing Applejack's pie delivery, Scootaloo seems to know something about how सेब Bloom sleeps that, (@ least does not let it show), that Sweetie Belle does not know about when Scootaloo is noticing how Sweetie Belle is starting to fall sleep as "Apple Bloom" द्वारा saying: "Sweetie, no, आप gotta sleep like सेब Bloom !," & Sweetie Belle उत्तरों द्वारा saying: "How does she sleep ?", & Scootaloo उत्तरों back to Sweetie Belle द्वारा saying: "Like she does everything, with sass". All of this, @ least in my mind, seems to lean to the direction that Scootaloo may very well have some relation to Applejack. If u still seem to disagree w/me about all of this, then let me know, द्वारा telling me what u think you're opinion is on all of this.

Since when was Scootaloo related to Dash? She just looks up to her. That doesn't mean she's related to her.

What about Pound Cake and कद्दू Cake?

They are siblings, even though both their parents are earth ponies. Mr.Cake did say how it was possible for the twins to be one pegasus and one unicorn-maybe something about one of his relatives being one and the other, but he was going way too fast for me to understand it, and it still baffles me.
