wah so much like tvb drama series, caleb come in...WHY??
he suspicious why no news on Sandy for a long time or
Sandy started to to treat him not the same as before...
or may be caleb saw u sent her home.

if choose to be with Sandy, go ahead but do it far-far and secretly

Else leave her alone, if she has no decision.

especially he already "warn" u in nice way, worry next warning will be nasty one, i guess.
