Tyrion finds out that Renly is dead, which is not great news because now everyone seems to be joining up with Stannis making for one big army which is probably headed his way soon. We also learn that Renly's corpse has vanished (more sorcery, or someone hiding a secret?). The Flower Knight Loras has gone a bit mad with rage and won't join up with Stannis, so Tyrion thinks maybe he can be charmed to their side, possibly by getting Joffrey to marry some female relative of his, Margaery Tyrell.
Littlefinger seems suspiciously keen to help out with that plot. And Cersei is suddenly being suspiciously nice to Tyrion. This can't end well.
