biking is nik's primary mode of transportation, so when she met freddie she would've been pretty excited to have company for biking as a sport, not just necessity. i think getting into camping probably happened after she met him, she's trying to be the typical boulder camping enthusiast but 99% chance when they camp in the extreme cold she's gritting major teeth like "yeah np i don't need all 10 toes, hypothermia try me"
