Lost 9 p.m., Channel 5
For reasons that are either too complicated for my feeble brain or, you know, too nonexistent, no one has even considered rounding up original passenger Walt for the return to the island. Whatever. The writers haven't forgotten about him, and Malcolm David Kelley (above, front, with Harold Perrineau) is scheduled to appear in tonight's episode, which is about Locke's fateful mission off-island. Remember the bond between Locke and Walt?
