He got early to the Laboratory, and...

...there, he saw this happening!

 And react saying (something like):

"W-What are you both doing?"

 Backstory for this Situation (first time happening):

"Dra. Priscila Sing, asked it her colleague,

Dra. Priscila Iing, could lend her some clothes,

But what happened is that, while she was wering

Them (the clothes), she being as jumbled as She's

normally is, got them dirt, but in a way that she can't

take the stain off, she tried to argue that it wasn't

her fault but, there something more...

Before Dra. Iing lend her Clothes she said that:

'If by any mean, you got my Dress: torned, stained

or ripped in any way, I'll make sure that you pay it,

And I won't want any type or thing, I'll need you to

do some things for me... and looking by what we

normally do here, i guess that you copy me?!'

So that it came to this, and that's also why,

Dra. "Iing" is wearing Dra. "Sing" dress!

(if you look on the other drawings, normally she's

wearing this dress or some variation of it..."

But as He catched them, doing this... well

I think that something might happen to him!
