What did he suggest they do? Well Jacen had a number of ideas none of which they'd probably pan through with. People might have a bit of an issue with some of them and he supposed the priority had to be making people safe. And finding out where his sister was. He actually found himself thinking what Jaina would do and smiled at the thought, she'd be a little more sensible probably. Only a little, if he'd wanted sensible he'd look to the example of Tenel Ka.
"I suggest we look around the neighbourhood. Find people not possessed, get them here. This can be the base for now. Then we have to contact the complex, or at least the Winchesters or anyone that might know what we're up against. We find food, we find people who can stand guard, set up shifts. We surrvive Sunshine, until such time as we can work out something better. What do you think?" He thought it was a pretty good idea as it happened. But he waited for her backing on it. Because that was what he should do. Taking complete charge of things. Well it probably wasn't the most sensible plan.
"We should probably decide soon and get to it" he added, looking across at the boy wondering should he just leave the illusion up for the duration. He'd probably feel better for it, Less traumatised. Kids shouldn't be involved in stuff like this.
