When Thomas arrived in the Chinese Himalayas, he spotted Nia making her way along the mountain tracks, who was still angry with him, after being abandoned in Arizona. After accepting Thomas' apology, an avalanche caused by Thomas' yelling and whistling swept Nia away towards the edge of the mountain cliff.
Thomas tried to pull Nia to safety by himself, but a rock underneath her got dislodged, nearly causing both of them to fall. Luckily, Yong Bao came to the rescue, and helped Thomas pull Nia to safety. After the snow had died down, the breakdown train was brought to lift Nia back on the rails.
Thomas later came to the Himalayas to try to find a runaway water wheel, and later helped Yong Bao rescue Lei.
