Achilles had accompanied his mother as she asked. He had mixed feelings with this situation as it stood. His father in the picture after so long felt like a shot in the back. He was happy, finally content with where his life was going and he was thrown a curveball. His mother was severely distressed which made Achilles instantly defensive.
He stepped inside after her, politely declining any alcohol that was offered. He didn't rely on vices to calm his nerves, though at times more than wine seemed like it could benefit him more than not. He didn't believe in being excessive about it. He would not begrudge his mother the option though if it helped still her frazzled nerves.
