Alphinode was always annoyingly pretentious (Glade Eistenian busted his reinfliting bubble in 3.0 because I certainly would of if given the choice)

As far as Minfilia, I think subbtle changes may be between Male/Female dialog (or maybe it's just me) but Minfilia seems to Lean on the MC alot starting in 2.2 after the first encounter with Elidibus in 2.1. So she at least sees us as a cofidant if not a friend.

Thancred seems to back you up alot after you save him because we saved his ass big time.

And Y'shtola seems to have grown a sense of awe towards us as of 3.0's conclusion.

Yda being the Ditz she is and Papalymo putting up with her all the time seems to make them alot more relaxed and friendly.

And Uriange (as a legacy player at least) seems to almost KNOW we're the same WoL from Cartenou.

Also, as a DRG, I loved the "We Got This Bro" vibe Eistenian has in certain CSs.
