This is our second Re-Cast for this character. The first VA had to quit due to personal Irl troubles. The same goes for the second one.

Levin is a character that first debut in Episode 5 of the series. He has since had multiple appearances. I will attach the playlist of the whole series below this explanation so you can view it in case you'd like to. 
Levin is a friendly guy with a bit of sass. He's around 17 years old at the current point in the series. During the events of Episode 9 however he killed one of the members of the enemy team. He is left feeling remorse and guilt however that fades to the background when his girlfriend Amber joins the team. In his current state he is mostly a happy, confident man who is happily dating Amber and close friends with Simon and Oliver. He still feels some guilt over his past actions however has bottled most of this down for now.

These lines are all already in previously released episodes (the first two in Ep 9 and the last one in Ep 10) so if you want to see how the previous VA did it then you can find it there.
Below's a playlist of everything that's in the first season for now (more episodes to come):
