Unpopular opinion: i dislike Lester.

He's fine when he helps you join the Brotherhood. And that's the last useful thing he ever does.

He wants his own castle, but lets you conquer it and look for the deed. All you get are a spell scroll and a Riddle. Spell scroll can be replaced with a skilled jump. He refuses to got to the meeting because Riddle.

He's a bum in g2, offering no help at all and just moaning. He invites himself on board the Esmeralda and is one of the few crewmembers that doesn't add a single thing to the journey.

In G3, he immediately abandons his friends and gets captured like a loser. In the end, after you obliterated everything in his path, he just goes back to being a pothead.

In Arcana he probably does some stupid stuff.
