I... Sorry, I didn't think you would take it so seriously. Well actually, I thought you'd treat the issue with some urgency, but to lose sleep over it is... well... "not good" would be the understatement of understatements...
Well, good news is I've already made a solution. Originally I thought keeping a bunch of time travelers in Central Park would be a fairly simple task... but given your reaction yesterday I've been thinking the job I gave you might have been a little unfair. So, I've decided to take matters into my own hands to make life a little easier for you so you don't have to keep a watchful eye over the park at all times.
I put a barrier around the park is what I'm saying.
[NPC] Naru:......A barrier.
Yup. Installed it last night. Don't worry, I made sure to program it so only you and your family could freely move through it.
Now you won't have to worry about anyone escaping and exploiting their vast knowledge of the future on an unsuspecting present. The barrier will keep them all inside like one big butterfly net. Unless they destroy the barrier somehow.
But they would have to be really strong
to do that, and I don't think anyone like that will show up any time soon.
Speaking of which, I checked the park this morning and it looks like we caught someone! From what I can tell they showed up some time last night and they're really upset that they can't leave the park.
