WMATA Metrobus 2014 NABI 42-BRT Hybrid

Seen here is a fast ride last night on the J2 towards Silver Spring Station with a 2014 NABI 42-BRT Hybrid #8061. These buses are rarely sent out on weekends, so I went ahead and decided to catch this one.

After the J2 Metrobus that goes from Silver Spring Metro Station to Montgomery Mall, which is currently located in Bethesda, Maryland, which is a city that lies in Southern Montgomery County, Maryland, goes on Maryland Route 410 past Connecticut Avenue, does the J2 Metrobus that goes from Silver Spring Metro Station to Montgomery Mall stop at both Bethesda and Medical Center Metro Stations?
