We all know nine-year-old Sheldon Cooper will grow up to be the rather odd man he is today in The Big Bang Theory.
But one of the delights of watching spin-off prequel Young Sheldon, which returns for a second season, is seeing how it all unfolds.
Iain Armitage plays the child prodigy whose interest in advanced mathematics and science are at odds with his family and his small-town neighbourhood, where all that really matters is church and football.
Sheldonโs parents, George (Lance Barber) and Mary (Zoe Perry), do their best to try to get him to fit in with his schoolmates. But heโs also out of kilter with his siblings, Georgie (Montana Jordan) and Missy (Raegan Revord).
Only his beloved, mean-talking, hard-drinking grandmother, Meemaw (Annie Potts), really understands him.
When TV WEEK was invited to meet Iain and Annie in London, we saw how close they were off-screen too. During our chat, Annie put a comforting arm around a rather jet-lagged Iain who had snuggled up to her on a couch.

Iain Armitage is back for season two.
Iain, 10, then revealed that he hadnโt seen any of the The Big Bang Theory before landing the role of everyoneโs favourite fussy theoretical physicist.
โItโs not really aimed at my audience level,โ he says, โand I donโt really watch that much TV in general.โ
But Jim Parsons, who stars as Sheldon in The Big Bang Theory, narrates Young Sheldon and serves as an executive producer, helped Iain understand the character.
โHeโs awesome and we get along very well,โ Iain says of Jim.
โA lot of the stuff he taught me was about two years ago, so my brain has absorbed it and itโs easy to get into Sheldon now. I donโt have to think about it as much as I used to.โ
Though itโs clear Iain is a bright and curious kid, he confesses he doesnโt know what heโs talking about for much of the time on the show when heโs espousing all manner of scientific theory.
โI just kind of make my mouth pronounce the words,โ he says with a laugh.
โThey tell me what it means, but Iโm definitely not smart enough to understand.โ
Guiding Sheldon through life is Meemaw, and when Annie (Designing Women, Love & War) is asked why she thinks they get on so well, she looks down at Iain, cuddled up beside her, and smiles.
โWell, we didnโt have to work on that very hard, as you can see,โ Annie, 65, says.

Sheldon has a ally in his worldly-wise grandma, Meemaw.
โI have three sons of my own, so I was just happy to have a little boy in my life again,โ she says. โHeโs very fun to act with, because he is a good actor.
โMeemaw makes no bones about the fact that Sheldon is her favourite grandchild. She likes the others, but she hardly has the time of day for them.
โShe senses Sheldon is unusual and that he needs her because his parents are terrified of him. Sheโs not afraid of him โ and she can teach him things he doesnโt know, like poker. Very useful things!โ
In real life, Iain, the son of actor Euan Morton and theatre producer Lee Armitage, prefers studying history.
โIโm actually home-schooled,โ Iain says.
โI like science, but itโs not my best subject. When Iโm filming, I have to do school work during breaks, but thatโs OK, because I love school.โ
