[Shiro's spent the last few days doing what he can. Look, he's not used to being without his team and sentient space lions, there's only so much he can do-- especially surrounded by people with magical abilities that makes his abilities, in comparison, seem kind of slight. And diplomacy was always Allura's area of expertise, really. But still, that doesn't mean he's going to sit aside and do nothing, although mostly he's just been helping to collect supplies and fishing (advanced alien tech arm is actually not bad for that).]
[Today, the relative eerie stillness and quiet makes him think it's a "calm before the storm" scenario, which means he's spent the morning focusing on reinforcing the tree bridges, since they hardly seem sturdy and the last thing they need if the floods increase is an unclear path to get to everyone. He's also been trying to firm up the treehouses as best he can with the limited supplies, trying to guess where potential leaks would be and stopping them before they start.]
[For now, he's in the middle of working on another tree bridge, strengthening it and tightening it up as best he can. If you approach to try to cross, he'll glance up and give an apologetic smile.]
Ah, hold on, I'm almost finished. Then it'll be safe to cross. [He tried to time it out to work on these things before a lot of people have to cross, so oops.]
