Tim jokingly sends Bernard:

Basically every night, but one night, he forgets to, and at first Bernard doesn't think much of it, but he still texts Tim anyway because they always talk before bed and say goodnight to one another, but cause Tim silenced his phone during patrol, he doesn't answer so Bernard slowly starts freaking out. After a few hours of spiraling and no replys from Tim, he goes to the manor and sneaks in cause it's past Tim's 'allowed to have people over curfew' and when Tim isn't there (cause Tim is patrolling as Red Robin, hence the curfew), Bernard goes into full panic mode, and he finds Red Robin on the street and Tim, obviously worried about Bernard, asks what is wrong and Tim doesn't know whether to laugh at how funny the situation is (and how paranoid his boyfriend is) or cry over how much Bernard cares for him, and so Tim is like "of course I'll help you, let's not get dramatic, I am sure he is not dead, oh, I'm sure he's okay, probably even closer than you think" and now he can't take out his phone cause Bernard will recognize it, and they won't actually find Tim cause Red Robin is Tim, and so they just go on an adventure all night and by the end of the night, Tim finally tells Bernard, and Bernard doesn't know whether to break up with him because he saw Bernard going through panic attacks and freaking out and he still didn't say anything, or if he should hug him and tell him how he's so glad he's okay, or if he should bombard him with questions about superheros, supervillains, and the like. He settles for a hug, a free pass for something major, and a discussion on a rooftop over 24 hour minimart coffee (that tim had to pay for).
