OOC: Well, it's like this:
Splat's eagle character, Pseok, is taking Dave's character, Roland, to Los Santos. He left first, then the characters Havoc mentioned took off in the jet, which has since overtaken Pseok and is heading for the same place.
Silvia, on the ground, saw Pseok carrying Roland, and thinking that this was a bit unusual, mounted her horse and followed after Pseok on horseback.
Then, your character, ahead of Pseok and Silvia but behind the jet, hopped on his giant falcon and followed after the jet. At least, that's how it appears from what you've said.
Understand now? Or have I confused you even more?
