You and Jasper first met when he, Clarke, Finn and You went on a road trip to find Mount Weather.

After you saw a river, you decided to jump into it and swim.

The others were about to join you - until a river snake arrived and tried to kill you.

Jasper jumped in the water, and somehow managed to rescue you, just barely getting hurt himself.

You escaped with only a few bite marks, the worst one being a small scrape on your cheek due to the rocky waters.

You and him instantly bonded, and it didn't help that you and him had to share a cabin, thanks to Bellamy.
