A respondent is someone who answers to a case in court. This term is commonly used in the civil sense, with a person in a similar position in a criminal case being termed the defendant.
If the Respondent was not served in time and shows up at the hearing, the court may proceed even though service was not timely. Any adult 18 or over, other than you, can serve the papers. Technically, service can be made anywhere the server has access to the Respondent including a residence, workplace, or hangout.
