Best Supporting Actor: Mmm, it could be Bridges because I think he could definitely win a second someday, but I'll go with Patel since he did win BAFTA.
Best Supporting Actress: Williams.
I actually forget Patel won BATFA, lol. Looking it up that would basically mean he was the only supporting actor nomination, that year that won a major award that wasn't Ali. That actually is a great reason to think he might have been second.
