The fast overnight ratings are in and somehow Chuck hit a season low with last night’s amazing episode. “Chuck vs. the Push Mix” pulled a 1.7 in the 18-49 demo with approximately 5.5 million viewers tuned in. Could the winter storm hitting a large portion of the country be to blame? The Cape also hit series lows with a 1.5 rating, although Harry’s Law bounced back with a 2.1. Perhaps the final numbers will give us more insight.
