Seiren was still flying through the air when Uriel's dash skill was deactivated. The reason why she felt so heavy was because with his enhanced speed, all of his movements required a lot more strength as the force applied would be the same but in much less time. In fact, if Uriel used just a bit more strength, her life could have been in danger.
What seemed like almost a full minute to Uriel, was only a second, but in that short second the table was broken, Seiren had been thrown far from them and Uriel's hand was caught in Jon's tight grip.
Now that his speed was back to normal, Uriel couldn't help but be amazed at the incredible reaction speed displayed by Jon. Somehow, he was able to block Uriel's attempt without even so much as stop his reading.
