Poor Onni! It can't feel good to want your family to stay when, for whatever reason, they apparently don't want to. Or at least Tuuri doesn't want to, Lalli doesn't have an opinion on the matter because he still has no clue.
Oh yeah, electric boat engine btw. Hey it's the future, cool things get to exist, like flying skateboards (well, those don't exist in this story.) the Icelanders have managed to develop some useful stuff to use their overflowing supply of electricity on, and they've been graceful enough to share their technology with the other less developed nations. So no steam engines to be seen here, sorry.
Tomorrow we'll see if they even make it on that boat or if it's just "oops, missed it. Adventure over".
