Oh...well I'm of the believe that Alexis throughout the entire series wanted Blake back...no matter what she might say...But yes they had loads of moments...and She 'changed her mind' from hating him to wanting him back more than a few times...E.g. in season 7, their both in Singapore on business, the oil rig that their on explodes and Blake ends up in the hospital. Turns out he has amnesia and think he's living in, ehm, was it 1964, and that Alexis and he are still married...and they spend a few days in Singapore till Krystle turns up...I'll let you watch the rest yourself...but it was definitely more than a moment!
