Last week the maid found Roxy's underwear. This week Rudy still had it. Either:

1) The scenes are not chronological, or
2) Rudy had 2 pairs, or
3) The maid gave it back to him....


.. as for MFauli's question - yes Rudy can fuck Sylphie.

Age-wise he looked quite a bit more mature and taller. I'd say he's 9 or something.

The kid with the bruise did look suspicious, but I figured Rudy just pegged water at him really hard.

We still low-key got to see further magical development by Rudy. He's still self studying and now can mix two spells simultaneously without chanting. In fact, I wonder how a normal person would do that anyway - would they interleave two spell chants together, or say them both sequentially before activating afterwards?
