Some accounts held that John and Gillian were real, corporeal beings. According to these, John and Gillian first met their grandfather in 1960s England. They knew he was some kind of inventor, but had evidently never seen him or travelled with him when they found the TARDIS in an empty yard. They entered and he acknowledged them as John and Gillian. During their visit, John playfully touched a button on the console and the TARDIS took them to the 30th century, where they helped the Thains defeat the invading Kleptons.
