Sylvester is enthralled in some white board calculations while Paige and Walter are going over Scorpion's books. Happy approaches Walter, "I need your RSVP."

"You know I'm coming. I already agreed to be Toby's best man." Walter replies matter-of-factly.

Happy lifts her eyebrows and stares at Walter in her inpatient deadpan manner.

Walter moves over to his desk, checks a box on the RSVP, and hands it to Happy. She starts to walk off but turns back after glancing at the card, "Do you have a plus one?"

Walter seems caught off guard, "What?"

"You didn't indicate if you were bringing anyone. So are you?" Happy asks.

"Um yes," Walter falters, "yes I am." He misses the disappointment on Paige's face.

Happy grabs a pen checking the box and retreats to the elevator shaft. Formerly the Timothy Armstrong Commemorative Garden, it had now become wedding planning central for Toby and Happy. "Add two to the catering count." Happy announces as she tosses Walt's RSVP on the table.

"That's going to put us over the limit to use the smaller banquet room." Toby notices the latest RSVP. "Wait, that's your backwards check on Walt's RSVP."

"Yeah… he left it blank so I asked and he said he had a date." Happy replies.

"Was Paige in the room when you asked him?" Toby inquires.

"Yeah…" Happy shrugs.

"He was posturing. He doesn't have a date and we can still use the smaller banquet room." Toby states.

"And if your wrong, Doc? We'll be a plate and seat short and look like jerks." Happy answers.

"I'm not wrong about this. I know Walt and we are on a budget. We're not going to spend $1512 more to accommodate his macho ego."

"You'd better be right. If I look like a jerk on my wedding day, your wedding night will suffer." Happy warns.

Toby dials his a number on his cellphone, "Val, yeah it's Toby Curtis. I just wanted to confirm the numbers we discussed are correct and things can proceed as discussed." (Pause while Val presumably responds) "Yes, thanks. We'll see you day after tomorrow." Turning to Happy, "There, all settled." He kisses her on the cheek, "We should probably turn in early… got to rest up for our parties tomorrow."

Happy growls. She didn't know what Paige had planned, but was sure that it would not be her scene. Unbeknownst to her, Toby was having the same thoughts about Walter's version of a bachelor party. Toby had asked Cabe to steer Walter along, but had since found out that Walter had come up with an idea and had kept it a secret from everyone not wanting to spoil the surprise for Toby.
