After getting in their car and driving to HMCHQ  (human-monster cooperation head quarters),the two females and their new monster friend made their way inside of the building and towards the front desk...

"Hey,is ambassador frisk available for today,we need to see them ASAP"

"I'm sorry but ambassador frisk is having a family day an-Oh my! What happened to this poor monster"

"We don't fully know yet but it's pretty urgent,are you sure you can't call them in"

"*sigh* if it's truly urgent..."

The receptionist then proceeded to call up someone who red presumed to be the ambassadors assistant because a nice,motherly,sounding woman had picked up the phone and said that the ambassador would be right over after they were done doing whatever they were doing

Timeskip:

Red was sitting nervously outside of the ambassadors office,slightly rocking back and forth on his chair,his uncomfortable mannerisms were due to him seeing who he suspected of be the ambassador when he entered the office

He seemed to be a tall and menacing goat man with blonde hair and beard and large pointy horns on his head,basically,he was fucking terrifying...

"Excuse me,skeleton,please enter"

Red stood up and made his way into the room...

Red entered the room cautiously,for all he knew this could all be a trap,a dark twisted joke that his boss was playing on him,he sighed, knowing this was not the case,after all he did know better,plus this was way too big and full scale for his boss to do...

"Sit"

The large goat monster ordered,but not an angry or demanding order,to be honest it was more of a request really

Despite this,Red still did as he was told,taking a seat on the chair next to him

"So red,I am quite sure you know why you are here,do you not?"

"Y-yeah mr.ambassador sir"

"Oh I'm not the ambassador,I'm just the assistant"

"Well then who's th-oh my god really?"

"Yes,the ambassador is over here"

Just as he said that,a small human stepped out from behind him,it was a...child?...

"Pffftt ahahahahahahahhahahahahaholy shit you're the ambassador,your fucking tiny,oh crap this is amazing"

Red burst out laughing,drawing the attention from everyone in the room straight to him

"Hahah...heh..."

when he finally stopped laughing and had finished catching his breath he looked around,realising the silence of the room he began to blush furiously in embarrassment

"..."

"Are ya' done?"

"Uh y-yeah Sorry"

By now red was just...well...red...(pun game on point)

"Good,now,down to business,who are you"

"Oh um I-I'm red"

"Okay,so red where ya' from"

"The underground"

"Mhmm,capital?"

"Snowdin,actually"

"Strange,I've never seen you there before"

"Oh,um,I was out camping with my boss when the barrier broke"

"Hmm,Okay,So is your Boss still down there"

"Y-Yeah I think so,but he wants to there so don't bother looking for him"

"Mhm got it"

Frisk was writing down notes on what looked like a clip board which made red very uncomfortable

"And you have nowhere to live"

"Yup"

"Okay,seems we have to put you into the monster relocation program"

"The what?"

"It's a program we have set up for situations like this and from when the monsters first came to the surface,basically we place you in a home like what you previously lived in when you were in the underground,we then try to find you the same or similar kind of job or school if you are a younger monster"

"That...is actually pretty clever"

"For now,until we can do that,you will have to stay with me and my monster family since we live in a big place and it would be the easiest,cheapest and quickest solution"

"Uhh okay,so are we going now or?"

"Yes we shall leave now my child"

"Got it big dude,let's go"

Red went outside to the car that had been waiting for the ambassador and he said his goodbyes to the two kind campers who had helped him out,they asked if they could take a picture with him to show their son since they were married and had adopted,he agreed and they took a picture,after that they hugged and red got into the car...
