Well, during this scene, Snake is actually upstairs. He has Homer at gunpoint, and orders him to show where the family valuables are hidden. It should be explain once the first pages are ready.
Also, I decided to draw the rest of the family trying to hop their way out of the house, looking for help. They make it outside, but failed to escape after tripping over their water hose since it was so dark outside. Snake take notice and decides to take them hostage.
Marge, Bart, and Lisa would soon be held inside the back of Snake's getaway van. Bart would offer some resistance, but the situation would remain hopeless. Then I guess, things would be left at a climax, with Homer left inside the house, all tied up, while Snake takes the rest of the family away.
Note: This doesn't include Maggie, though.
So that's the direction I plan on taking, there will be more to follow over time as I try to fill the requests, so please look forward to them! ^^
