Sky was the grandmother of Billy Lane.
When Billy was kicked out by his parents for being gay, Sky took in her grandson. She was a hippie, into health food and anti-violence. She volunteered at the local library, which one day was overrun by zompires. Billy, having trained as a vampire hunter, and his boyfriend Devon rescued her, after which she let her son live with Buffy Summers, provided that he Skype her every sunrise to let her know how he was doing.
