Of course, Richter eventually ends up with armor... and I seem to recall that happens after the continuity reboot, so plainly he doesn't need to buy any now.

Of course, the big story here is that Frankie found a new mummy. What will this mean for their relationship? How does one even find another mummy?

Well, of course that last one is easy to answer: in Castlevania continuity there are two mummies already, Akmodan I and II. There are also a few that are dropped in as random enemies in a couple of games, I seem to recall. Circle of the Moon had a mummy enemy.

Can't be that hard for Frankie to find one if he was looking.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
