bus route question

[mamajoan.livejournal.com]

When the 89 bus goes to Clarendon Hill, does it turn around and come back through Davis Sq.? in other words, if I'm in Winter Hill and I get on the 89 that says "Clarendon" rather than "Davis", will it eventually take me to Davis?

Of course on a normal day I could just get off at the rotary and walk down College Ave., but well, have you looked out the window lately?

btw, I did try to look it up on mbta.com but the map is unclear.
