Concealing the Truth
They had nothing to say to each other.
Cadman forced her into this situation so Katie had no choice but to play along.
A date with McKay- Great! She wasn't even remotely attracted to him, so why go along with the plan? Simple-Laura.
Why couldn't Laura see? Why couldn't she see that she wasn't interested in McKay? Why couldn't Laura see that she wanted her, not McKay?
Why couldn't Laura see and understand that Carson wasn't right for her?
Would she admit her feelings out aloud to end this sham, to stop lying to McKay and herself? Probably not.
