I'd say add a BMP of the "Home Sweet Home" splash and wait until it is no longer found before proceeding. Once the splash is gone, you can assume the char is in the house.
As for doing it specifically with R2, I'm not sure.
Long ago, the '90s Nicktoons lived together in harmony. Then, everything changed when the century turned. Only Avatar, the best of the 2000's Nicktoons, could save them. But when the channel needed it most, the show finished. Four years passed and Mike and Bryan created the new Avatar: Legend of Korra. And although the show itself is great, it has a long way to go before it can live up to The Last Airbender. But I believe Korra can save Nickelodeon.
