Greta Thunberg in The Last of Us HBO Series #shorts

Can someone tell me, what i sGreta Thunberg doing in the last of us
So we got a trailer for the last of us HBO series
and the first thing I thought of when I saw Bella Ramsey playing Ellie was Greta Thunberg
I dont know why but she looks different then when was in Game of Throne
Why does Bella ramsey look like the autistic Greta Thunberg in this live action
No disrespect intended I am still going to check out the series but everytime I see a clip of Ellie now I just see Greta yelling at me with the old classic
Are you watching the watching the Last of US on HBO..
