Please strace this running process, e.g.

  sudo strace -p 347

(where 347 is the PID from ps)

Attach a sample of the output

There is no fsck process running anymore at this point:
root 332 98.0 1.3 76484 51924 ? R 09:37 25:23 mountall --daemon
(no child in ps fauxwww output)

(and no plymouth either obviously :)

I noticed the same thing just now: my disk was checked and at about 60% progress the plymouth screen suddenly disappeared and the boot sequence continued. I assume that fsck died away for whatever reason...
