Jenny is very new to this thing called technology. Even more so with the Internet. A combination of the Doctor's know-how and Jenny's natural curiosity (the curiosity of a child, only a few weeks old) doesn't bode well for the rest of the universe. When Jenny's ramshackle little spaceship passes by a galaxy, said galaxy breathes a collective sigh of relief (then says thank you when she shows up and saves them all).

Anyhow, the Internet. She's not allowed to use it anymore. By orders of the boys back at home, who are very busy planting crops and building new cities to actually visit Jenny but they do send holo-mails now and then to check up on the Time Lady (in training, of course, it's a slowly earned title, now it has no academy for her to graduate from properly).

See, the thing about Jenny - sweet Jenny, energetic Jenny, the one with the gun but never kills, that Jenny - is that her fingers are like minature sonic screwdrivers. Touch something and it opens up completely to her, reveals their innermost machinations. Jenny knows it; she takes advantage of it freely. A gift to the heir apparent, she thinks. She likes it. So do the boys back home. (And Martha. And Donna. And Captain Jack - especially Captain Jack).

So imagine those fingers working on the Internet, touching that massive system of connections that span across the world. She's liable to come across something, right? Maybe files on her genetic father? Torchwood security seems to be lax these days, as with UNIT. Jenny plans to meet this 'Lethbridge-Stewart' man one day, ask him questions, listen to his stories of working with the Doctor. But not now; she's too busy running and touching everything in sight.

Then there's all the people, all using the Internet. Jenny wants to talk to them all, listen to them, help them somehow. It's what her father would want, after all - for her to save people. Only her Internet just doesn't reach Earth, oh no. In her little space pod, she's got a map of the universe in her modem, all laid out in zeros and ones. And one way or another, they all know the Doctor. They're perfectly harmless, living their lives in peace and normalcy. Some deal with aliens now, others do private detective work. One lad even has a rock band. Jenny doesn't think much of their 'music', but they've got heart, she'll give them that. It's when Jenny starts talking to these people that things get out of hand and the boys from home end up finally leaving their lush new world to clean up one of Jenny's messes.

Yes, Jenny isn't allowed to use the Internet. Last time she did, she ended up playing several rounds of intergalactic Hearts with River Song and her two children.
