If he loves sam, he loves sam.If not radhika then somebody/something else will make him realize that.
If he does not love sam, he does not love sam...and 100 radhikas or anybody else will not be able to make him believe otherwise.
Give neilooo (yeah that is my nick name for him) some credit people, he is pretty smart.
And don't bash radhu for the most non sensical of reasons...wait for the real ones if you really do want to bash her.
