"Right, you've got a crooked sort of cross... That means you're going to have 'trials and suffering' --
sorry about that ..."
-- Harry Potter reading Ron's tea leaves (PA6)
Tea leaf symbol from Unfogging the Future meaning “trials and suffering” (PA6).
- Ron does suffer after getting The Cross in his tea leaves. His leg is broken as he is pulled into the Shrieking Shack by Sirius Black in dog Animagus form (PA17).
Latin "crux" meaning Roman torture and suffering while hung on a cross
The cross is the symbol of suffering in Christianity. The word comes from the Latin "crux" referring to the Roman torture of nailing their prisoners on wooden crosses or "crucifixion" as they did to Jesus. source: Wikipedia

- One of the most painful spells Harry encounters is Lord Voldemort's Unforgiveable "Crucio," which comes from the Latin root "crux" just as cross does. And there's also "horcrux" which appears later in the series as a symbol of ultimate evil (HBP23), and the fact that Harry visits King's Cross Station during his near-death experience (DH35).
- But of course Harry was reading Ron's tea leaves not his own, so what is another connection? Possibly the fact that Ron is the one who dives into frigidly cold water to retrieve the Sword of Gryffindor from the forest pool in the Forest of Dean. When Harry sees the underwater sword it appears like a "great silver cross" (DH19).
- The Prisoner of Azkaban movie reverses the reading of the tea leaves so that Ron sees a "wonky cross" and the sun in Harry's future, when the canon is that Harry is reading those in Ron's cup:
Professor Trelawney: Your aura is pulsing! Are you in the beyond? I think you are!
Professor Trelawney: Look at the cup, tell me what you see!
Ron: Oh yeah... well, Harry's got a sort of wonky cross... that's trials and suffering. And, uh, that there could be the sun, and that's happiness, so... you're gonna suffer... but you're gonna be happy about it... (PA/f)
