wonder what it will be like when I go back in time,â Toby said.
â When you go?â I said. âYouâre not really planning to risk that, are you? Youâre lucky going into the future didnât mess you up.â
âI have to try it,â he said.
âLook, going forward didnât do anything bad. But, think about it, going back could make all sorts of weird stuff happen. Youâve already been there.â
His face got this blank look, like he was so deeply lost in thought that he might as well already have sent his brain back in time. âYeah ⦠itâs deep. I guess thereâs only one way to find out.â
âI donât think this is a good idea,â I said.
Toby flashed me a grin. âI never said it was. But I have to see what happens. Someone had to be the first man in space. Someone had to be the first to try a vaccine or test out a parachute. Someone has to be the first to go back in time.â
Before I could come up with any sort of argument, Toby grabbed another time grenade from the box, gave the stem a twist in the other direction, then pushed the top in with his thumb.
I flinched at the click. Toby didnât vanish. But we looked at each other, both silent as we digested what had just happened.
âCoolâ¦â Toby finally said.
âWeird,â I said.
It was definitely weird. And hard to describe. Toby had gone back in time. But heâd gone back to where he already was. And where I was. So, all of a sudden, I had a memory of there being two Tobys with me for a little bit. The second Tobyâthe one whoâd traveled back in timeâhad popped up maybe ten seconds ago. Heâd looked at us, flashed the typical Toby smile, and said, âAwesome. I figured it would be like this. I wonât be here for long.â
Then, heâd vanished just when Toby number one sent himself back in time.
âWow,â I said, âthat was amazing, but you really took a big risk.â
âWorth it,â Toby said.
âWhat if youâd stopped yourself from sending yourself back?â I asked. That was just one of the dozens of questions that shot through my mind. âThen, thereâd still be two of you here,â I said.
âMaybe I should try that,â he said.
âMaybe you shouldnât,â I said. âYouâve been pretty lucky so far.â
âYouâre right. But thereâs one other thing to try right now. I want to go back at the same time you go forward.â
He set two time grenades, one for the past and the other for the future, matching the symbols, though one was blue and one was green.
âThat sounds even more dangerous,â I said.
âIt will be the greatest thing ever,â he said, holding one of the grenades out to me.
âWhat will be great?â
We both spun toward the voice. Oh no. Rooney had found us. Heâd probably heard me when Iâd been screaming for Toby right after heâd vanished.
âNothing,â Toby said, dropping his hands to his sides. âWeâre just fooling around.â
âGive me those,â Rooney said. He took a menacing step toward Toby.
Toby looked like he was going to argue, but when Rooney clenched a fist, Toby sighed and handed over the time grenades. âBe careful,â he said.
âDonât tell me what to do.â Rooney held up the two grenades, one in each hand, with his thumbs on the stems. âIs this some kind of game?â he asked.
âStink bombs,â I said, blurting out the first thing I could think of that might make him drop them.
âSweet,â Rooney said. âLetâs stink up the woods.â He pressed his thumbs down on both buttons.
âNo!â Toby shouted. He reached out to try to snatch the time grenades away. But it was too late.
Rooney traveled to the past and the future at the same time. Unfortunately, he also occupied all of the time
