Singular or Plural After an Indefinite Pronoun?
Most indefinite pronouns refer to a single person or thing. Therefore any personal pronoun or verb related to that indefinite pronoun should go in the singular person.
She hates anybody who wears flip flops at formal occasions.
Someone rings my doorbell at five in the morning, every morning, damn them!
Clue: if the indefinite pronoun ends in -thing, -body, -one then you can safely assume it refers to one person or thing and any verb or pronoun that follows it should go in the singular person.
All, any, more, most, neither, and some can refer sometimes to one, sometimes to more than one person or thing. For that reason, each can take either the singular or plural person, depending on the context. If you’re referring to several people or things within a unit, you can use the plural.
Neither knew the answer but they gave it a try and guessed it right!

When talking about a group of people or things, and animals and you look at them as a group rather than as several individuals then you should use the singular person.
All is well!
