Joseph was at Junior's door with Cody by his side (as you see in many sml episodes) he knocks and greets Junior as he opens the door

"Wassup, dude." It was raining

"Can we come in? It's a bit cold out here."

As Junior let's Cody and Joseph in, they sit on the red couch (as you see in every sml ep)

[Be whoever u want. Which ever character! You decide what's next.]
