Had Tev survived Scourgeprom, he would have become a blood knight, serving faithfully until the re-ignition of the Sunwell. Then Paladin!Tev would have had a major crisis of faith in the blood knight order that would have seen him off to Northrend, then helping throughout most of the Cataclysm (as opposed to Tev who opted to stay in Northrend to help clean up after the fall of Arthas and to keep an eye on ~things~.) He would have jumped on the first ship to Pandaria. Basically anything that would have kept him as far away from Silvermoon as possible, until he feels he’s attoned for what they did.
