Tedd is not a decker per say, he has the skills but lacks the equipment. He is that kids that knows everything there is to know about decks but is unlikely to afford a deck of his own. Then he unexpectedly got into debit making the decker dream even further away.
You have Kira that is his best friend - but they are friends, kind of like family. The debit to Ganderson (probably bought off from the mafiosi that Tedd accidentally wrecked his car, crushing. Tedd tries to gather the funds to get an auto shop and probably do some mechanical work to compliment Kira's side business with hardware repair and upgrades. Perhaps a good place to start the game would be with Tedd in his Thundercloud Morgan crushing into the expensive car in the middle of a chase. (always fun to start with a bang). We can RP Ganderson bailing the kid out of the mob (probably as a favor to Kira) and who knows what happens next.
