1) Almost every freaking character in S4 is an ancestor of someone from s1 (kind of to a stupid extreme even)
Um... are they? I think most of them were just homages to characters from the first game, none of them are actually confirmed as being related except, Elenor for being a member of the Silverberg family.
Rachel and Camille was an obvious one, it would be interesting if Camille was descended from a long line of red haired bounty hunters with a tendency to develop a soft spot for their most evasive target.
Etienne had the exact same face as Kasios, and both performed for flowery mansions.
Gary and Ema resembled Max and Sancho, and Gary wears the eagle medallion (not quite sure what the creators were doing there, though. Gary and Ema weren't exactly knightly, they were just some regular couple sticking their nose in people's business)
Paula looks a like a female Kirkis (not that Kirkis looked terribly manly in the first place)
Katarina has a similar look to Cleo
Kika has Valeria's face, hair colour and shoulder pads, but every suikoden game needs a falcon user, so I guess the designers thought, why not just have a sexy pirate version of Valeria?!
