met with members of his own faction to take back control of mafia in MTL.
and of course Vito wasn't out there doing these hits himself.
as far as meeting w/ pietrantonio after his release from jail seems odd considering pietrantonio was allied w/ salvatore montagna in an alliance to overthrow the Rizzuto faction.
there is less than a year between pietrantonios dec,2011 attempted murder and the oct,2012 release of Vito.
considering some of those murdered afterward were just as complicit in the attempted downfall of the Rizzutos i can't see Vito meeting w/ pietrantonio for anything.
