So what happened on the island? Some Jack-Kate-Sawyer action?
Pretty much. As often happens with castaways stranded on a tropical island, a love triangle developed between Todd and Tea (Todd suddenly realized he loved Tea and wanted to be with her after everything they'd been through) and Ross (who, being no dummy, saw what a hot ticket Tea was). Many fun, sexy island times were had, and Todd and Tea ended up having sex for the first time (despite the fact that they'd been previously married and essentially in love for years).
And then, what, happily ever after? Come on, this is Todd you're talking about!
Exactly. Todd, being Todd, was still hung up on Blair, and Tea could see that, so she gave him leave to build a makeshift raft (!) and sail out to sea (!!) despite the fact that Llanview isn't all that close to the south Pacific, geography-wise.
And what of Tea and Ross? Did they build another raft? Signal a passing airplane? Find a mysterious hatch?
We ended up hearing that Tea and Ross were rescued from the island, but that was the last we heard of Tea at all until she returned to Llanview last year to help Todd with the small matter of being accused of imprisoning Marty and plotting to steal his daughter's baby.
