For question 1 and 3, go through your Nuke app after the screens where Robin is dancing, right before Cece enters.
2. When sitting down beside Cece, bring up your phone and send a message to her.
Good luck. :)
How exactly do you get the pin code? I've pulled up the nuke app just like you're saying and it doesn't show anything.
You need to scroll all the way down to the photo Kira posted of the two of you in the bowling alley and press the prompt :)
