The Doctor's Mate.
June Smith/Jones or as herself and everyone else call her Jet. She is a 109 year old Time Lady but she looks 19. She is on her 5th regeneration. She lives with Sarah Jane Smith and is best friends with Martha Jones.
She has light brown hair and forest green eyes that darken to moss green when she is angry. She's 5'5.
Jet is funny, sarcastic, energetic, smart, loyal and hot tempered. She loves the Earth and humans and finds them to be fascinating and amazing. She loves pears but despises bananas. Her favourite coluors are yellow and pink.
Jet and the Doctor are soulmates. Jet knows that her soulmate is alive but the Doctor still thinks that all Time Ladies are dead.
