Tonita Castro and guest star Sal Velez, Jr. shine on “Go On” this week. But…

Go On is one of NBC’s s strongest new shows so far this season, both with critics and viewers. The large ensemble cast is one of the reasons, and Tonita Castro is a key part of that cast. This weeks episode also feature Sal Velez, Jr. as a Latino gardener who begins as your stereotypical sheepish domestic and ends on a strong, high, and surprising note. You can see it on NBC.com or hulu.com for free, and at least for the next few weeks. But one quesion: how come the rest of the “group therapy” group is in the big posters, online and on buses all over the place…but Tonita Castro isn’t in the shot? Hmm.
