Mark's POV:
Tom: Exactly, and do you guess where did he lead to?
(We strike our head as no, Tom played another footage, which is Mona's Hospital, and I am shocked by looking at the attacker is just behind us in the hospital.)
Mark: So, he followed us to the hospital on the same day?
(Tom nodded his head as Yes.)
Tom: And he stayed at the hospital for the whole night, look at this...
(Tom pointed out the video, and the attacker just sits behind us in the chairs, and he observes all of us while Mona is explaining to us about Rubeus uncle's condition.)
Mark: What the hell is going on, Tom?
Did he stay at the hospital to kill Rubeus uncle?
Tom: Maybe, look at another clip, you will get more clarity...
