Adam is shown to be hostile and very unfriendly, even saying "I don't have any friends" when Sarah tries to explain to him why he should make a video in honor of Jonah. Judging by the chats shown in Volume 4, he is very unfriendly and probably gets into arguments with others. His personality probably changed as a result of MLR, as Evelyn says he used to be the "nicest guy" in her MCPD statement. It may also hint at the possibility of replacing it as an alternative.
