I am not your team mate

Sparky Dark happens to be one of the most experienced pilots in the whole galaxy but she does not know that there is a team of amazing pilots that save the world. She may not be very reliable since she always disappears for a long period of time and never tells anyone where she was during their battle. She seems to be very rebellious and has hated being with a team. After losing her brother Tyler Dark, she couldn't trust anyone and now is on her own mission to save her friends from harm. However her ship gets busted due to a small impact of meteoroids and she gets rescued by Voltron. During her time on their ship, she gets very snappy at every single member of Voltron and Keith tries to help her. Sparky tells him that she is not on his team and she will not be their friend either.
