Season 8 - promises and threats *SPOILERS*

[Tuesday Pajamas]

I think the key word in Lorre's quote is unbelievably. Definition from dictionary.com:

[uhn-bi-lee-vuh-buhl]
adjective
1.
too dubious or improbable to be believed.
2.
so remarkable as to strain credulity; extraordinary

That sums up Sheldon's "growth," wouldn't you say?

THAT was nicely spotted CassandraElise! What a choice of words...!!!! In that case I AGREE with Chuck.
