I love how everyone’s reacting to Mark wanting to go with Kieran as a secret murder plan.
No one will be forgetting Mark attacking Kieran for what he said about Julian anytime soon.
Right now Kieran is experiencing a phenomenon first recorded by one Simon Lewis in TMI, called “having the car”. Having a car, or being the designated driver means you are always and automatically involved in any plan, no matter what peoples’ personal beliefs on you being present are.
