I expect Face to neither fully activate nor fail completely.

I think it will activate, but only partially, either because someone already tempered with it, or because the one Face-node that Wendy alrady destroyed stops the chain-reaction half-way.

I don't really begrudge Happy for that line. As far as actual explanation goes it's bullshit yes, but it is just something that Happy would say. It's like that "it worked because you are awesome" line that he dropped in the Lullaby arc when Natsu wondered how he got rid of Erigor's storm-mail.

And the reaction of the other Exceed to the line for me was more like "Yeah whatever Happy... sorry we thought you'd say something sensible" than actual agreement.
