I think Jonas and Gabriel are dead because: when Jonas climbed the mountain, he was in pain because he fell off his bike and he scrapped his knee and twisted his ankle. Maybe when he fell of his bike he might of gotten dirt into the scab and got infected since he didn’t clean it. And that could’ve gotten into blood stream and gotten into the heart that could’ve made him sick. Jonas and Gabriel also had water from a lake, and who knew that the water was clean? It could’ve been dirt and infected with bacteria and germs.

When Jonas and Gabe reached the top of the mountain, how could a sled, the exact same one from the memory The Giver gave him, just appear out of nowhere, and exactly in the spot he needed it? It’s like a coincidence! Plus, wouldn’t it be covered in snow and or blown away?! It’s nearly impossible!
