Reflecting on all of the connections he has made while filming the series so far, Duncan begins to wonder what it actually means to feel connected.

He decides to speak to somebody who actively chooses to remove technology from their life as much as is realistically possible, to see how connected they feel. He finds Hamish, a young man who makes Pictish crafts, who takes Duncan to a secret loch to go rowing in coracles and to camp overnight by the fire the way the Picts used to.

Duncan then heads off to meet Michelle, a fashion blogger from Kenya who now lives in Perth. With more than 11,000 followers on Instagram, Duncan asks how she stays connected with all of her followers.

Duncan's next stop is to meet young painter Ellis O'Connor, a millennial living on North Uist. Ellis is happy in her own company and thrives in isolation, and she shows Duncan the benefits of getting out of the city to a smaller community where people look out for each other.

With loneliness being listed as the number one fear of young people today, Duncan wonders what you do if you want to make a new friend. It鈥檚 often harder to meet people as you age, so he tries advertising for a new friend using friendship apps, which leads him to meet Dana. The pair meet up to see a film - but is making this new connection worth it, or is it just awkward and uncomfortable?

Duncan then decides to try and reconnect with his friend Raj, someone he lost touch with and hasn鈥檛 spoken to for years. Raj is now married with kids - will he even remember Duncan?

Reconnecting with Raj goes better than expected, and feeling hopeful, Duncan ties this in with his thoughts and conclusion on the series as a whole, reflecting on what has he learnt and how is he feeling about the future.
