While the jury is still out over at CBS on whether Scorpion will be brought back for at least one more season, Dominoes, the series’ Christmas episode pulls out all the stops and by the show’s end, there should not be a dry eye in the house. Viewers watching the installment over the Internet should probably cover their laptop or keyboard with waterproof material. There are a few chuckle worthy moments and as usual they center around Happy and Toby. Oddly, for a Christmas show, Ralph’s newly resurfaced father Drew does not make an appearance. Walter’s sister, Megan does figure in the holiday and family themed episode with enough presence that if the show is brought back for a second season, she will most likely come with.
