Imagine an AU where Lee is alive but Eggsy still ends up becoming an agent and getting together with Harry. Because Eggsy has since moved in with Harry and Lee has not seen either of them in a while, he invites them over for a family dinner. During dinner, Eggsy asks “Daddy, can you get me a knife?” and without thinking, both Harry and Lee stand up. Daisy is confused and Michelle thinks nothing of it since Harry’s been sort of a mentor figure to Eggsy for a while…

But Lee? He knows.
