It makes me wonder what's going to happen when Danielle meets Angela.
It has been so heavily trailed that Dani is going to use the watch on Angela that it would be surprising if she did and it worked.
The key thing about 401 and 403, I suspect, is that Claudia was evidently a necessary cog in Julian's plan to kill Jakob. And if it's true that Claudia can't leave the New York harem's home, that does perhaps suggest that Jakob is likely to be dropping in there.
For what it's worth, I've previously speculated that there might be a connection between Claudia and Astrid, based on nothing more than their German names.
