[Bells]

Bless, I think he'll survive - I'm expecting BB realises that he's quite old and has taken stuff like that into account.
He probably wanted to do something 'outrageous' in his later days, plus he mentioned he's had a fascination with BB for a while.

Whilst he's certainly not going to be the most exciting HM in there, I think it's good that he's given the experience a try and it's still too early to determine what kind of personality he has anyway.
