There has been much criticism over how many Marvel characters have appeared in the series to date but there certainly appears to be a lot more coming.
Last week we heard Lady Sif will make an appearance and Stan Lee himself is due to guest in the next new episode T.R.A.C.K.S. which airs Feb 4. We also know Bill Paxton will appear as Agent John Garrett in a number of episodes and today a little spoiler was leaked on Twitter.
Titus Welliver (Agent Blake) has just joined twitter (@Welliver_titus) and he says:
On the set of Agents of SHIELD with my buddies @maxitois4real and @clarkgregg

Looks like Agents Blake and Sitwell will be back later this season!
