I didn't say it, but i suspect the "i knew it all along" may be coming too.(Maybe) Emily is subconsciously trying to prevent her son from repeating his father's mistakes by cock blocking.
Santiago has selective face amnesia. But I hope the reveal isn't going to be something lame like Santiago knew all along he was his son, but chose not to reveal it for some grandiose lame reason. (Otherwise known as I knew you were talking about me all along Elena.)
I don't which is better, a second "i knew it" or Santiago king of the dum-dums? The second one is at least funny if people start giving him grief.
And another parallel with the MC not being the brightest guy very often
