Harrison always talks slow (nothing to do with his age) and the show is so fast paced, I felt sorry for him, but I think he genuinely enjoyed himself.
His reply to acting in another Indy film was good, and as he said he could act the older Dr Jones like Sean Connery did.
The Episode 7 question was handled well, mentioned, joked about then moved on.
Harrison's hairstyle was the most 'Han Solo' style he's had in years.
