Echo's smile lingered as she was acknowledged, and then her attention went to the shelves and cabinets. Reminiscence crept into her thoughts as objects caught her gaze. Her childhood home was once filled with many objects like these - her mother's tastes. Many similar items Echo broke. Many similar items Echo sold. She wondered if her mother came to this shop at all to buy these things. And how often as well - the prices on these items wouldn't have Echo purchasing any item for a very long time.

 It was difficult to not have her attention waver when the customer being served was so bold. She mentioned the Riverperson, which sparked the thought of an unlikely friendship between a character so loud and one so quiet. At least that was Echo's judgement when she spotted the cloak associated with the ferry.

The latest comment about falling short to buy a product particularly caught her interest. Two customers in a shop with shallow pockets? Echo mused to herself. In a shop like this, what are the odds?

”Fair enough, I don't blame you.” The mysterious individual replied casually with a hint of class. ”Really how many people would you trust that show up to be helpfully ominous, am I right?” They added with a chuckle of sorts. Regardless, they weren't particularly surprised with what Undyne said, but accepted it anyway. ”We'll see, I suppose.”

The dropped spear earned a hum of curiosity, but Undyne was left to speak as she wished for the time-being. ”Crazy is an understatement, I'll say that much.” Now, she was cooking with gas. Undyne really did catch on quick when given the right information, almost always. ”The worst part about that is... If the world rewinds again, you won't know and we will be back to square one.” Thus, the problem was put out on the table, and only two people so far would potentially know for sure. ”It is said ignorance is bliss.” Perhaps in this case specifically, that was true. Who in their right mind would want to have this kind of knowledge?

”Again, I don't blame you. I came prepared, that's all.” The armored one shrugged their shoulders slightly. Their tone didn't precisely convey the outright desire for a fight or physical confrontation. It was far more close to acceptance— accepting that it could be possible, coming from Undyne. Despite this, her answer was 'satisfactory' so to speak, since the armored enigma nodded slowly, listening intently. ”I see, I wouldn't exactly call wanting people to be the best them they can be 'foolish'. That begs the question though; what will you do to get there if our King's methods are flawed? Do you think he will listen when anyone tells him his plan was wrong? Because I think it was exactly that.”

Ambiguity wasn’t exactly one of Undyne’s strong points, so she wasn’t surprised by the comment he made. Perhaps even a small part of her respected that touch of forwardness. The blue monster did however, blink with mild surprise at the bow that followed; his conduct made it more difficult for the scaled monster to maintain her dislike for him – at least, as much as she had earlier, “I don’t trust you.” she stated rather bluntly yet still respectfully in reflection to his bow, “The way you keep talking – even at the Core – you act as though you know something is going on, or is going to happen.”

While she continued to frown and as much as Undyne wanted to keep her guard up, one of the four spears behind her spoke otherwise when it shattered like glass after hearing his assertion; and what he had continued to say just confirmed what she had said earlier, “This is crazy.” Undyne muttered under her breath as she turned around to look out to the waters of Waterfall; through the gaps of her spears. Ironically those glowing weapons felt like bars of a window within the collapsed hall, like a prison She then continued with a clearer tone, “People like you and Sans knowing about this timeline stuff. How it’s happened before – many times as you’ve said but the rest of us been left in the dark about it, completely unaware.” That yellow eye turned skyward to stare at the glistening rock ceiling, “So that would mean that we have been down here longer than we have thought.”
Her hand curled into a tight fist which shuddered lightly, ‘How many times have I betrayed June?’

When the Captain turned around she was met with that convicting gaze and instinctively her expression hardened, as though to challenge it, “For real, before I really wanted to kick your arse before but now I don’t really see how that’s going to benefit anyone. Even if it is still tempting.” she said simply before pausing to give his questions some thought, “Everything is so different now but my goals are still the same. I may not be where I want to be now but I will be there to liberate monsterkind to the Surface one way or another. Maybe Asgore’s methods weren’t exactly the most ethical but we can still find other ways to free everyone and I still want to stand by his side despite everything. A pledge of my life to our king isn’t something I take lightly and I cannot just walk away from someone even when things start to get difficult or murky.”

She then shrugged, “Some find it foolish but I say there isn’t enough monsters out there that you can count on.”

Delighted to that she was home, Sans' smile grew a little wider; as did his soul beat a little faster, despite maintaining a cool and calm demeanour. He couldn't stop the chuckle from escaping his teeth when he heard her reply.
'So. This is a thing now? Telling jokes through doors? Heh. This rules.' he thought to himself.

As articulate as ever when entertaining others, the skeleton followed through with coming uo with an answer on the fly.
"Adore." he said casually, maybe even with a slight trace of affection to the word. Sans waited for the predictable answer before following through, "Adore is in between us. Can I come in?"

He really couldn't even stop himself from snickering at his own joke either while he waited patiently, "Hehehehehehehehehehheh."
