The outermost colored ring on Captain America's shield goes from red to white for one shot.
At various times throughout the show characters make unbelievably illogical decisions. Namor fails to recognize the smell of alcohol and mistakes it for a pool of water, Captain America takes the suggestion to hide in a pond when an experienced soldier would use solid cover like a tree, Dr. Strange doesn't use his magical amulet or cape to escape his trap, or any of his spells.
