"Do you really count on him?"
Translation:Naprawdę na niego liczysz?
This pronoun has three forms:
1) go 2) jego 3) niego
1) is a non-emphatic third person pronoun used for both masculine accusative/genitive and neuter genitive.
2) is the emphatic (emphasised) counterpart of 1)
3) is used instead of 1) or 2) if it's preceded by a preposition.
Jego also happens to be a possessive pronoun but that's because all third person possessive pronouns are derived from (look basically the same as) the genitive of their respective personal pronoun.
