Fredo the p*do?

Watched G2 for the first time last week. Something seemed a little off about Fredo’s fishing scenes with Michael’s son. I get that he’s dumb and his social skills are probably limited to what he’s good at- hosting parties etc. He has no family of his own and maybe doesn’t have much experience with kids. But still there’s something kind of creepy about his interactions with Anthony. Did anybody else ever get that vibe?
