Saying (λεγοντας). Accusative present active participle agreeing with "the eleven and those with them" in verse Luke 24:33.

Indeed (οντως). Really, because "he has appeared to Simon" (ωπθη Σιμων). First aorist passive indicative of οραω. This is the crucial evidence that turned the scales with the disciples and explains "indeed." Paul also mentions it (1. Corinthians 15:5).
