Will spots something shining and "glistening" in the distance, and the Marshalls discover a deposit of matrix crystals hewn into the side of a rock outcropping. They begin to test various crystal combinations (red & blue = explosion), but the last combination they try paralyzes Rick Marshall's nervous system "like lightning."
It's here that "The Search" gets interesting. Holly must get Marshall back to safety at their High Bluff shelter, while Will must convince Enik to heal his father. It's a test for both kids -- a family crisis wherein each must grow up enough to face heavy responsibility. To save their father (and survive the day...) Holly and Will must each display creative thinking, problem solving and persistence. And they must do so completely independently.
And it's not always easy. Holly realizes she can't lift Marshall's weight up to the mouth of the High Bluff cave, and engineers a "counterweight" to him (in a basket...). Al the while, Grumpy the T-Rex looms nearby.
As for Will, he is tempted when Enik, the Altrusian, opens the time doorway and it happens to flash on the Marshall's time period. Enik urges Will to jump through; to take this single opportunity to return to his life. But Will can't leave his family behind, and Enik is shamed by his self-sacrifice. "Your self-control cannot be stronger than mine," Enik notes haughtily.
In the end, Marshall is healed, and realizes that the younglings aren't so young anymore. "Both of you saved me." "Both of you are growing up."
"The Search" has some good character moments, but my favorite was no doubt the instant at High Bluff when a dying Marshall talks seriously and emotionally with Holly. "You're just as headstrong as your mother was...bright, strong, never took a back seat to anyone, including me..." he says. This is a nice humanizing moment, though we know - of course - that Rick isn't really going to expire.
The only weird moment in "The Search" involves Enik's last scene. He has just healed Rick Marshall using two blue crystals, and then he speaks with the Marshalls for a moment. Suddenly, he begins to gesticulate wildly and exaggeratedly...totally unlike the cool, calm Enik. I wonder, was Walker Edmiston unavailable for that scene, and replaced by a lesser double? That's my best guess, because Enik isn't usually so effusive with the body gestures...
Another strange moment. Early in the episode, when the crystals explode, it looks very much to me like Spencer Milligan is standing too close...and is a little singed by the detonation. Go back and watch, and you'll see. During the next scenes, his eyes are tearing and his voice is shaking. And the explosion certainly looks dangerous...
