Honestly, Terry has such a potential to become a really complex character alongside Claudia in season 6. Because I think he partly is aware that there could be something 'fishy' going on, but Claudia, Viren (with whom he bonded in season 4) and in extension Sparklepuff seem like the only family he has. Especially considering they are way more accepting of him than the other Earthblook Elfes. And now Claudia, whom he really loves a lot, has lost her leg. Someone had cut Claudias leg off and you can't tell me that as Claudia lies there crying in his arms that Terry wouldn't harbor a big dislike towards whoever did this.
And Terrys reaction to Aaravos would certainly be interesting. Espcially if Aaravos would come up with a ritual that in the end ends up prolonging/saving Viren and also a way to elleviate or at least easy Claudias problems regarding the missing part of her legs.
Besides, all that Terry must have heard of Aaravos must have been quite positive. And he can't really harbor any delusions to what Claudia can and is willing to do considering he is aware of the things she did and went through in order to save her father. And Aaravos is someone who holds the knowledge on how and is willing to bring someone back from the death.
Also, there still is the factor that while Terry has proven to work as the groups and especially Claudias conscious and good side, he had still been willing to kill for Claudia in season 4.
