Wow so his brother hadn't seen him in a month?? Raphael couldn't even begin to wrap his mind around possible 'how's' and 'why's' - so he didn't bother.

"Well I'm here now. Not goin' anywhere." He stated. He was about to say something else but something Don said made him glance at his brother incredulously. "Say what? Mechawhatsit aliens? What's that in English?" He half teased with a grin. The fact there was possibly non-human's and aliens here didn't bother him too much, considering his own genetics. Besides, he supposed it was similar to when they got zapped to D'Hoonib that time.

At the mention of going ninja on the folks in charge, an intrigued gleam shone in Raphael's eye. Something almost predatory and he too, lowered his voice. "Ya have huh? Good. I've been lookin' forward to a good ol' fashioned brawlfest." It's been a while in his opinion. It was too bad his buddy Casey wasn't here to join in either.

The fact that Leo and Mikey weren't there was a dampener on the situation, but all in all, he was glad to see Don and have some family around. He could tell that his brother felt the same. He moved away enough to nudge Donatello towards one of the couches, grabbing his envelope and plate of food and glass of water he was working on before joining him at his side.

"So what's this business ya said you were workin' on?" He asked curiously.
