This is definitely the most Awkward shock-kiss we've seen thus far - I don't think Angus is really smooth enough to pull it off.
Also, this is the first one not to get its own panel! Does that mean that it's not as momentous as the others?
If so, I agree - it's cute, but it didn't really take me aback the way that the others did. Maybe because it didn't come TOTALLY out of left field like the others did - with this one, we basically already know that they're "dating", so it isn't all that shocking. Plus, look at Faye's face - there doesn't appear to even be a glimmer of potential that she might return said kiss.
Mainly, I think it's the artistic choices that do it - i.e. it doesn't have its own exclusive panel. That, and the look on Faye's face.
