Jeremy Harrington (born September 22, 1985), known online as Jeremy Elbertson and better known as Jerma985, is a livestreamer who has collaborated with Joel on multiple occasions. He was first known for his numerous Team Fortress 2 video commentaries which began his channel but has since produced many videos featuring a variety of games and comedy sketches. Now his biggest creation is The Rat Movie series *cough* *cough* BSI > TRM *cough* *cough*
The rivalry between Joel and Jerma itself started in Vinewrestle 2019 when Jerma decided to hack the stream and invade the event, leading to him winning the tournaments. Joel and Jerma still make collab streams and still hate each other as much as they did in their first encounter.
Just like Joel's rivalry with Rev, Joel's rivalry with Jerma is just played for laughs, as the two do not actually hate each other and nobody should attack one another (*wink wink* ;)).
